My science fair project was soaking red cabbage in boiling water and pouring water into four chemical substances (i used laundry detergent, vinegar, lemon juice, and baking soda) and depending on the color the water changed seeing if it was an acid or base. (it changed pink for acid, blue/green for base). What would be the dependent and independent variable in that? Please help!Can you please find the dependent and independent variable in this?
Kind of an abstract question. The independent variable is the one that you essentially have control to change, which makes me think it is the type of substance you poured the water in to. The dependent color, depending on the other, would then be the color that your solution turnedCan you please find the dependent and independent variable in this?
the independent variable would be the substance that you're pouring water into...the dependent variable is the color of the water since the color DEPENDS on the substanceCan you please find the dependent and independent variable in this?
Firstly, the *color* depends on the acidity/alkalinity of the solution. Your conclusion depends on the color, but the changes in color are due to the different changes to the HOMO-LUMO gap (part of the electronic structure) of the indicator molecule in red cabbage as the molecule undergoes different chemical changes in different pH's ... (yay for orgo!).
As you may guess, your independent variable is the stuff you're testing. Whether laundry detergent is actually laundry detergent is not dependent on the color of some arbitrary solution it is added to. (Well unless you want to go all philosophical on me.) But the color depends on what types of substances are added to it. Your dependent variable are the values which show the results -- stuff you wouldn't have been able to ascertain without actually performing the experiment. (If you happened not to know any better about red cabbage.)

How would I write my answer so that it will express the answer in terms of the independent variable?
The answer I got is dw/dt = -4sin8xsin4y + 4cos8xcos4y * 5t^4
It says that the answer is right but in order to get credit, it has to be answered in terms of the independent variable.
The problem is: Use the chain rule to find dw/dt, where w=cos8xsin4y, x=t/2 and y=t^5.How would I write my answer so that it will express the answer in terms of the independent variable?
In your answer, replace x by t/2 and y by t^5. Then your answer is a function of t, the independent variable.

How to compare a constant variable against independent variable.?
I have constant variables such as male, female, non smoker and smoker.
how do compare each of these grouped factors with a independent variable abdominal diameter cm.
I have calculated mean, sd and range but how to I calculate there significance.How to compare a constant variable against independent variable.?
How can something be "constant" and "variable" at the same time?
Maybe what you have are independent and dependent variable. The abdominal diameter depends on whether the subject is male/female, smoker/nonsmoker. So the diameter is the dependent variable, and the sex (or smoking) is the independent variable.
Testing for significance is tricky; you can read about it in books and on the web.How to compare a constant variable against independent variable.?

What is the dependent, independent and the controlled variable?
in this experiment we have to find the best coin shiner using 5 coins and 4 different products (im choosing vinegar, coke, disinfectant and milk) we put 4 coins in the products for a period of time then take them out and observe the results.
in the report we have to state the independent variable the dependant variable and the controlled variable im pretty sure that the control is the untouched coin.
thanks for your help.What is the dependent, independent and the controlled variable?
An independent variable is one that's results do not change depending on other changes to the experiment. This would make the coin shiners the independent variables.
The coin will change due to the different shiners, therefore it's results are dependent on the independent variable.What is the dependent, independent and the controlled variable?
You are right about the control. I think that the dependent variable is the coins that you put in the different liquids, and that the independent variable is the liquids themselves, because "if x is given, then y occurs", where x represents the independent variables and y represents the dependent variables
Independent variables answer the question "What do I change?".
Dependent variables answer the question "What do I observe?".
Controlled variables answer the question "What do I keep the same?"."

You are correct on the independent variable. Dependent, I would simply say: insect deaths. I would think that control would be the amount of each product you use. Like how much dish soap, etc... That's what I'm thinking. I don't know the constant, unfortunately. Anyway, I hope that helped at least a little.

How do I find the independent variable?
I don't get how to find the independent and dependent variable because sometimes they alter each others outcome. EG. The distance a jogger runs depends on the length of time she runs.
In this question i don't know which is the independent variable because the distance depends on the amount of time she runs, but the amount of time she runs changes the distance!?!?!?!How do I find the independent variable?
The independent variable in this question is probably the length of time, and the distance is the dependent variable. I agree that this choice of example is silly, though.

a constant is what doesn't change in order to see the difference between after you changed your experiment/variable and before you changed the variable- REGULAR TAP WATER
the control variable is basically the same thing as a constant- REGULAR TAP WATER
the independent variable is the variable that you change- SALT + WATERhighlight

Is it possible to change the independent variable in a partial differential equation?
For example, I have a pde like this: dx/dt = k dx/dy (the 'd' refers to the partial derivative). Now, if the first independent variable, t is related to another variable, T, by the relation, dt = dT/m (here, 'd' is the total differential and m is a constant), can I write the original pde as: m. dx/dT = k dx/dy?Is it possible to change the independent variable in a partial differential equation?
You can definitely do that. In cases like this, you can kind of treat the derivatives like, they're fractions, even though that's not technically the case. You're actually using the chain rule, which states that dx/dT = dx/dt*dt/dT, then just rearranging some variables.

What is an Independent and dependent variable?
When you think of the word "independent" you often think of being independent and not needing anyone helping you to make choices, etc. In matters of science the word "independent" is the opposite! Meaning, the independent variable is helped along - or changed! The word "dependent" means to rely on someone or something to help you! But, in science the word dependent Variable means the opposite. A dependent variable stays the same. It is not helped along by scientists.What is an Independent and dependent variable?

In science, these are referring to the results. Look back to the problem statement of the experiment. More or less, it can be phrased as "How does _____ affect _____?" This first blank is the independent variable. The second one is then the dependent variable. The dependent variable is dependent on the independent variable. It is affected by this. The dependent variable does not stay the same. It varies. If, for example, you are doing an experiment, "How does temperature affect density of water?" You must know that the colder the water, the denser it is. That makes the temperature the independent variable. Let's say you are testing it at 20 degrees Celsius and 80 degrees Celsius. The dependent variable, the density, will not be the same, right?
Also, yes, the independent variable is changed. But that is why it is a variable. It is independent because it is not affected.
I hope this helps!What is an Independent and dependent variable?
Youve got it right and heres how i remember it, independent means not needing anything, because of a change, and dependent depends on others to stay themselves. Other names are
Independent:predictor variable, regressor, controlled variable, manipulated variable, explanatory variable, exposure variable, input variable
Dependent:response variable,regressand,measured variable,observed variable,responding variable,explained variable,outcome variable,experimental variable,output variable.
Hope this helps!What is an Independent and dependent variable?
Nope! You got them mixed up!
How you change the independent variable affects the dependent variable. For example, in a photoelectric effect experiment, an increase in frequency (the independent variable), changes the kinetic energy (the dependent variable). How the dependent variable changes *depends* on how the independent variable changes.
Independent variable is the only variable the experimenter changes, and he/she measures the changes of the dependent variable.bloom-

I'm doing an experiment where I'm using citrus fruit to light a tiny light bulb, like a Christmas tree light. I can only use one thing as my independent variable, which is what I'm changing in my experiment. Should I change the types of fruit, like an orange, lemon, and lime, or keep all the same types of fruit. Or, should I keep the same type of fruit and change the weight. Or, should I just change the type of light bulb?Which should be my independent variable for my Fruit Bulb science fair project?

Hypothesis is literally your best guess, so pick the drink with the most sugar and say "i think that blahblahblah drink will be the most effective because it has the most sugar, which is known to create energy." your independant variable is something that you keep the same for all of your test subjects -- something like the amount of energy drink.Can you help me find a hypothesis and a independent variable?
hypothesis: should be based on what the independent variable is
independent variable: could be the energy drink but it would be better if you researched what does each drink contain...it can be the combination of a common ingredient and the amount of it.

We will put some Steller sea lions in a simulated environment and give them a supply of both Pollock and Herring over a weeks course, and see which species the sea lions prefer over the other.What is the independent variable in this experiment?
The independent variable is the part of the experiment that you control. Like for example, how much food to give them. What kind of food to give them. What time of day to feed.
Anything that you control. Now the dependent variable is related to the I V. That's the part you cant control as a result of the IV. Here is a good ex. Lets say u put 2 plants out and give one 8 hrs of light and the other 4 hrs of light. Water the same. Now the light is what u control. But u cant control the growth of the plants....that's the dependent V. The growth will vary depending on the amount of light. Understand now???What is the independent variable in this experiment?

Assuming "Ceteris paribus" (namely soil type, envoirnment like temprature sunlight , equal capbaility of both individuals) you can have time spend on tending the plant as dependent variable.
Height of Plant = a x T + C
T = time spent
C= error term

T = time spent
C= error term
a = co-efficent of T
What is the difference between an independent variable and a dependent variable in science?
I think the independent variable is the one that you change and the dependent variable is what you are testing?? I'm not sure, please explainWhat is the difference between an independent variable and a dependent variable in science?
Yes.What is the difference between an independent variable and a dependent variable in science?
Independent variable is changed then the dependent variable is measured to come up with the accurate conclusion.

what is the independent variable in a science experiment??? and what is the dependent and the controll???Independent variable?
dependant varabile: A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable.
An independent variable is a factor that can be varied or manipulated in an experiment (e.g. time, temperature, concentration, etc). It is usually what will affect the dependent variable.
There are two types of independent variables, which are often treated differently in statistical analyses: (1) quantitative variables that differ in amounts or scale and can be ordered (e.g. weight, temperature, time). (2) qualitative variables which differ in "types" and can not be ordered (e.g. gender, species, method). By convention when graphing data, the independent variable is plotted along the horizontal X-axis with the dependent variable on the vertical Y-axis.
control: A control in an experiment is a group, sample, test, etc. that is used in comparison to the group, sample, test, etc. that the experiment is actually done for. Controls can also be samples in which the expected value is known. This is the part of the expirement that does not change.
Examples: In clinical trials the control group gets the placebo. In genetic experiments the control is usually the wild-type organism.

recent study reports that infant rats fed a special protein-enriched diet reached an adult weight 10 percent greater than litter-mates raised on a regular diet. For this study, what is the independent variable?
a. the rats given the protein-enriched diet
b. the rats given the regular diet
c. the type of diet given to the rats
d. the adult weight of the ratsIndependent variable?
c. the type of diet given to the ratsIndependent variable?
C. An independent variable is a variable that can occur without something else making it happen. The type of diet given to the rats should be random and not based on anything. therefore it's not caused from something else happening.

what would be the independent variable and dependent variable in this expierement. Melting chocolate with a light. Aluminum foil under the chocolate, the light placed 3 feet away, 10 easy points. i dont understand this whole independent thingsIndependent variable?
The independent variable is the one you can control; the dependent one whatever varies as you twiddle the independent one.
My guess is that the independent variable is the distance from the light to the chocolate, and the dependent variable thw time to melt the chocolate.
If you could vary the wattage of the bulb but not the distance, then wattage would be the independent variableIndependent variable?
I don't know what experiment you are trying to plot . For example say that you want to plot how long it takes chocolate to melt when you place the heat source, in your case a light, at various distances from the chocolate. The melting time DEPENDS on the distance of the heat away from the chocolate. Short distance = short melting time. You would then call the distance the independant variable (plotted on the X axis) and the melting time the dependant variable (plotted on the Y axis).
Another example: You want to graph how far it takes a car to stop from various speeds. So you drive a car at 5m/s. 10m/s, 15m/s......... 40m/s. You measure how far the stopping distance was when youi apply the brakes. Again, the stopping distance DEPENDS on how fast the car was travelling. The stopping distance is the dependant variable (plotted on Y axis) and the speed is the independant variable , which is plotted on the X axis.
To sum up: The independant variable is that which you measure as your base at some regular frequency. The dependant variable is what result you get from measuring the change at the frequency intervals.bourjois

In experiments, does the Control group form part of the independent variable?
Lets say there's an experiment consisting of two groups, a group of Depressed subjects and a control group of Non-Depressed subjects.. with certain drug treatments to be tested on them and measurements taken.
Would one of the independent variables be Depressed/Non-Depressed? Or does information about the control group not form part of the independent variable?In experiments, does the Control group form part of the independent variable?
Yes, the control group (and the experimental group) do constitute an independent variable. An independent variable is basically any differences in your sample that you explicitly manipulate (by assigning people to conditions) and/or make comparisons between.
So in the case you describe, a simple design would be
Depressed vs non-depressed, where you have 1 IV.
If you're varying the types of treatment used, you could have 2 IVs, being
IV1 = depressed vs non-depressed
IV2 = Drug type a vs drug type b vs placebo (placebos are often used as controls in drug trials)
Similarly a 3 IV design might be:
IV1 = depressed vs non-depressed
IV2 = Drug type
IV3 = Male vs female
An independent variable refers to the dimension on which they differ (e.g. their depression status, their sex status etc.), rather than what the groups you separate them into are within that (be it 2 groups, 5 groups etc.).

Describe how the dependent variable changes as the independent variable changes in a linear relationship. G?
Describe how the dependent variable changes as the independent variable changes in a linear relationship. Give examples. ThanksDescribe how the dependent variable changes as the independent variable changes in a linear relationship. G?
A mathematical relationship can be written as :
y =f(x) i.e y is a function of x
for a linear relationship f(x) is a linear expression i.e of order 1
for e.g
y= 3x or y = 2x+4 or y=-4x+2 etc.
Now, coming to the eqn y=f(x) it means f(x) represents a function in x and since y=f(x) ,y takes values according to
f(x) ..it means y is a dependent variable i.e y is dependent on x.It means if x changes in value, y will accordingly change its value.
FOR E.G
consider the equation y=3x+4
here f(x) is represented by 3X+4
when x=0 ,y = 3x+4 i.e 3*0 +4=4
so, when x=0,y=4
When x=2
y=3x+4 i.e 3*2 +4=10
so, when x=2,y=10 and so on
Hence we can see as the dependent variable y changes its value according to the independent variable x.

Could an independent variable in one experiment be a standardized variable in another experiment?
Could an independent variable in one experiment be a standardized variable in another experiment and vice versa? Please explain how and give examples.Could an independent variable in one experiment be a standardized variable in another experiment?
Yes, this can happen in any experiment where there a 3 or more variables - one independent, one dependent, and one controlled or standardized.
Simple example: series resistance circuit with variable voltage and variable resistance.
Experiment 1:
Resistance standardized (held constant)
Vary the voltage (independent variable)
Measure the current (dependent variable)
Experiment 2:
Voltage standardized (held constant)
Vary the resistance (independent variable)
Measure the current (dependent variable)
etc.
These experiments will demonstrate and confirm Ohm's Laweye makeup

What is a definition of an independent and dependent variable???
Thanks for your help!!What is a simple definition of a dependent and independent variable?
An independent variable is an "input" variable. It's usually something you can control.
A dependent variable is an "output" variable. It's usually something that you measure.
For instance:
f(x) = y = x虏
You can think of x as the independent variable and y as the dependent variable, because the value of y depends on the value of x. That is, you can plug in a value for x, and you get a value back out for y.
Plug in x = 1:
f(1) = 1虏 = 1
And you get out y = 1.
Plug in x = -2:
f(-2) = (-2)虏 = 4
And you get out y = 4.What is a simple definition of a dependent and independent variable?
a dependent variable is something that depends on another thing
and an independent variable is something that doesn't depend on anything...
like.... y = 2x + 4
y is dependent on x...because as x changes y changes..... ( in general term of graphing )
therefore.....since y is dependent ... then x is independent :)What is a simple definition of a dependent and independent variable?
An independent variable is one that can take any value you choose, maybe within certain limits. A dependent variable is one that is worked out from some formula or process.

What is the effect of Independent Variable on a Dependent Variable?
My honors Biology Teacher is making us do a science fair project and I need an idea. It has to be in the forum of the title. So "What is the effect of __________ on _____________" Which is the same as "What is the effect of an Independent Variable on a Dependent Variable?"What is the effect of Independent Variable on a Dependent Variable?
Examples:
What is the effect of lack of sleep on test grades?
What is the effect of music on plant growth?
What is the effect of antibiotics on earaches?What is the effect of Independent Variable on a Dependent Variable?
The independent variable is something you change
The dependant variable is something you change
The dependant variable 'depends' on what the independent variable is.
So a different independent variable will have a different dependant variable.

If you are not measuring anthing then you have no variables.
Your inputs to the systems are:
food (manure, sugar, etc)
bacteria
co-2
outputs are:
methane

The dependent variable is the number that changes based on the independent variable. The independent variable does not change.
For example. x + 2 = y
If x is 2; y is four.
If x is 5; y is seven.
X is the independent, y is the dependent. Because [ y ] depends on what [ x ] is.
Or, another example, if you've been driving 2 minutes, you are five miles away from you're home.
How far away you are from home DEPENDS on how long you've been driving.
So when graphing, driving time is independent; and mileage is dependent on driving time.
Best fit is a straight line that best represents the data on a scatter plot.makeup

Would the shape of the ice cube be an independent variable ?
Thanks %26lt;3What would be the independent/dependent variable in this experiment?
Yes.
The shape of the ice cube is independent because it is controlled by the experimenter before the experiment even starts.
The time for the ice cube to melt is obviously dependent on what shape was chosen.

How do i get 2 conditions from 1 independent variable?
Hi i have just started uni and am struggling with a psychology assignment where i have to create and use one independent variable with two conditions. Can anyone help as i know how to find I.V but not how to find two conditions. Many thanks in advance!!!How do i get 2 conditions from 1 independent variable?
I am not 100% sure, but this might help:
If the experiment was growing a plant, and the dependent was the height and the IV was amount of sunlight, two conditions would be outdoors and indoors. The IV can be changed (amount of light) in both conditions...

The independent variable is the one that you control. If you are adding or moving plants around water that then yes, plants would be your independent variable. If water is is what you are changing things around, yet leaving alone - it is your dependent variable aka: the variable that you are measuring.
You should have a control group. Water that you do nothing with adding or moving plants around. Just measure it as it is.

In this lab what is the control, independent variable and dependant variable?
Observing Osmosis.
Put 2 eggs in 2 cups of vinegar to remove hard shell.
Then blot and weigh it after 2 days.
Then put one in syrup and another in distilled water.
Mark the change of the mass.
So what is the control, independent variable, and dependent variable.In this lab what is the control, independent variable and dependant variable?
Not tricky.
The independent variables are the syrup and the water. They are what you varied in the experiment. They are different all by themselves - so they are independent. The dependent variable, the one that depends on the the other, independent, variable - is the mass of the egg after you subject it to your variables (independent ones). The control is the egg's mass without any solution, before you do anything to it. This control is what you used to show what would happen if you did nothing to the egg.
You might expect the water bath would cause water to move into the egg - water moves from higher concentration to lower - that egg would weigh MORE than the control egg.
The syrup would cause water to move out of the egg- water moves from higher concentration to lower - that egg would weigh LESS than the control egg.

I am doing an experiment to see whether my bearded dragon is instinctively drawn to either crickets or fruits and veggies. What is the control group, experimental group, independent variable and dependent variable?What is a control group, experimental group, independent variable, dependent variable?
do a different experiment. to do an experiment like that with only one subject would take too much time.

This is the hypothesis "Would video games affect your heart rate? My brother doesn't trust my answers so I need someone to prove me right!What would be the control, dependent variable, and independent variable?
Independent variable is the presence or absence of the computer game
The dependent variable is the change in heart rate
The constants are the conditions under which the test is carried out (same time of day, same length of exposure to the game or to no game) same batch of volunteers, each tested with and without the game. Same game used in all tests
Do our lists match ??

Statistics Question: should I throw out and independent variable it it has little impact?
I am preforming a regression analysis where four parts of a test are used to determine the impact on an employees future success. In stating my results, should I re-run the analysis and leave out the independent variable (which has very little impact on the success rating) and provide those findings also?Statistics Question: should I throw out and independent variable it it has little impact?
Are you using any model selection criterion? What the AIC or AICC values for the different models with and without the variable? Is the variable significant in an interaction? All these questions need to be addressed before you remove the variable from the model.
You can also conduct an F test for the reduced model vs. full model, here is a link to that information:

Most likely the goal of this question is to figure out if you have an arithmetic sequence. If that were the case, you'd have a list of numbers such as 2, 5, 8, 11, 14, ... that were all the same distance apart. (In this case, the common difference is 3.)
This question is actually phrased very strangely, though. Normally an arithmetic sequence would be something true of the DEPENDENT variable (the output of a function or sequence) rather than the INDEPENDENT variable (the domain, or the numbers you plug into a formula). The question still has to mean whether certain numbers are a set distance apart, but it's not quite as clear what numbers they're asking about. If it really does say "independent", most likely you have a set of points and you're supposed to be comparing the x's.neutrogena

What is the independent and dependent variable in this experiment?
I have a science project on common beliefs. I tested my common belief , buttered bread always lands on the buttered side. It landed on the buttered side 12 times out of 20. In order for me to fill out my worksheet before I can start my poster board I need to know how to answer the questions on the worksheet....so what is the independent variable + dependent variable in this project? do I need to do something myself to find it?
THANK YOU IN ADVANCE! (:What is the independent and dependent variable in this experiment?
dependent variable. a variable that depends on the value of another variable
independant variable. a variable that can be changed during the experiment
********
dependent variables are usually measured
independent variables are usually set
********
********
in the bread and butter experiment..
let's say you took 100 slices of bread. then..
(1).. used a sharpie to label the sides A and B.
(2).. buttered side A of 50 of them.
(3).. Tossed them all up in the air.
(4)... measure the amount of times A was face up
and saw these results...
A was face up 18 times with the buttered bread
A was face up 25 times with the unbuttered bread...
your dependent varible is whether or not the bread was buttered
your independent variable is number of times A was face up.
*********
I would be nice if you repeated the experiment a have dozen times or so and had statistics to back up your results. You should also propose a theory about why buttered bread lands butter side down. something like density of bread vs butter. objects orient themselves heavy side down in a gravitational field.. etc

What is an independent and dependent variable?
I don't understand the difference.
The independent variable is the one that doesn't change while the dependent variable is the one that changes.
Right? I always get these confused.What is an independent and dependent variable?
the independent variable you can decide which one is it. the dependent variable is a consecuence of the independen variable.
just think about candies. you can buy 7 candies by 1 dollar, so you could get an expresion like this
y = 7x
x is independent and y is dependent. if you have 5 dollars, but you decide spend just 2 dollars, so you get 14 candies. so x is independent because you decide what is this value. y is dependent because it is the result of what you decide as amount for independent variable.
Science lesson time! YAY! ok, so the independent variable is a variable that is changed in your experiment. For example,if your doing a expirement to see how food effects a racer's time, the independent variable is the food, because you just change that for the experiment. The dependant variable is what changes depending on the independent variable. In the example mentioned earlier it would be the racers time because it deends on what the racer had to eat
*note* this example was not tested nor do i know if food actually effects the time it's just a random exampleWhat is an independent and dependent variable?
The simplest way to answer the question would be to use the terms from the question itself.
The independent variable is what it says it is. It is independent. Its value is arbitrary, it could be anything you want it to be.
The dependent variable is what you are trying to test. It depends on the value of the independent variable.
For example, if you wanted to see how SAT scores affect college grades, you would have two variables:
1. SAT scores
2. College GPA
Lets say you make a hypothesis saying that there is a positive correlation between SAT scores and college GPA. That is to say that a student whose SAT scores are higher than average is likely to do better than average in college and a student who scores lower than average on the SAT is likely to do worse than average in college.
Now, just think about what depends on what. Your SAT scores do not depend on your college grades. You are way past SAT when you are in college.It is the other way round.
Thus, in our little thought experiment, the SAT score is the independent variable and the college grade is the dependent variable.What is an independent and dependent variable?
A change in the magnitude of the independent variable results in a change in the dependent variable.
Typically, in an experiment (for example) the independent variable is the one an experimenter has control over (how hard you press the gas pedal) and the magnitude of the dependent variable (how fast the car goes) "depends" on the magnitude of the independent variable.
you have it right , I always just try and remember that whatever is along the x-axis is independant and whatever is on the y-axis is dependant
Yup, you're right.hand soap

Can someone help me identify the independent variable in this experiment?
I am going to put 2 different containers with 5 seeds in each one. one of the containers will be placed somewhere were sunlight hits it all day long, and the other in tha shade but move it (so it can take sunlight) for half an hour each day. after the experiment is completed i am going to see the plant麓s growth rate... can you help me to identify my independent variable??Can someone help me identify the independent variable in this experiment?
The independent variable is the conditions you are putting the plants under; one plant sits in sunlight all day long while the other sits in the shade but move it for half an hour each day.Can someone help me identify the independent variable in this experiment?
The independent variable (the one changed by the scientist) is the amount of sunlight. The dependent variable is the growth rate.Can someone help me identify the independent variable in this experiment?
The independent variable, the one you can mess aroung with and change, would be the amount of sunlight. The dependent variable is the growth rate of the seeds.

Can Two Way Anova tell which independent variable is a better predictor?
For example
dependent variable = heart rate
independent variable = male or female
independent variable = natural runner or n
given a set of data, can two way anova tell which independent variable is a better predictor of the DV heart rate?Can Two Way Anova tell which independent variable is a better predictor?
You can compare the Type 3 sums of squares for the two IVs. If one is considerably larger than the other you would be fair saying it's a "better" predictor. Note that the ratio of the SS of some effect to SSTotal is called eta squared and is a measure of effect size similar to R^2.

What are the levels of the independent variable?
my project is testing do aerobic exercises increase the lung capacity. Im testing it with balloons.
my independent variable is the balloon, i just don't know what the levels aree .What are the levels of the independent variable?
There could be 2 possible levels: 1) How fast a subject can inflate a balloon to a certain diameter, and 2) The diameter that the subject can inflate a balloon to, in a single breath.
Be sure to include one group doing "interval training", which is the best way developed so far, to increase pretty well all parameters of aerobic training. Here's how to to it:

What is the independent/dependent variable and control for my experiment?
My experiment:
I tested 3 girls (teens), three guys (teens), 3 adults (female), and 3 adults (male).
I'm testing them on memory based on their gender, their age, and their daily activities.
What would be the independent variable, the dependent variable, and the control?
Thanks so much :)What is the independent/dependent variable and control for my experiment?
Dependent variable is when a variable in a research design that is free to change over a range of different experimental treatments. You have probably made a hypothesis that the dependent variable will change in some systematic way as the experimental treatments change. Examining the data that you generate will tell you whether or not your hypothesis is right.

What is the independent variable of this experiment?
I am "experimenting" if a certain brand of tire is going to last up to 33,000 miles. I have set up the experiment where I will drive a car with the tire on different road conditions (straight, curvy and rocky) for 33,000 miles in each condition. I will also be comparing that tire to another popular brand tire (lets say, Goodyear) and drive THAT tire on different types of roads to 33,000 and compare the result with my experimental tire.
What is my independent variable (experimental groups), and control? What is the dependent variable then?
Please help. Thank you!What is the independent variable of this experiment?
The independent variable for each tire would be the terrain, because you are controlling the terrain you're driving it on. The dependent variable would be the results.What is the independent variable of this experiment?

Income, because your expenses depend on your income.
(assuming you spend your money well of course, haha). It makes sense that if you make like $20,000 a year you'd manage your expenses according. So if you make like $50,000 a year you'd probably have different expenses.In an equation with expenses and income, what would be the independent variable?

An independent variable is that variable which is presumed to affect or determine a dependent variable. It can be changed as required, and its values do not represent a problem requiring explanation in an analysis, but are taken simply as given
More generally, the independent variable is the thing that someone actively changes; while the dependent variable is the thing that changes as a result.

Why do we only study one independent variable at a time?
Why do we only study one independent variable at a time?
I know it is the main cause of the whole experiment and that the dependent variable depends on the independent. If you had two independent variables in an experiment, you will not know where your results came from.
Help? Thanks in advanced.Why do we only study one independent variable at a time?
You can have several independent variables in an experiment. But you hold them constant, and look for differences in one at a time. For example, you can have sex and education level as two independent variables....dependent variable is "a behavior"...score on a test, something the subject does....you can look for differences in that DV in males vs. females...then between educational levels. You can be even more refined and look at differences in male college graduates vs. female college graduates vs. male non college graduates vs. female non college.....interaction effects. But yes, you do statistical analysis looking at differences in one IV, while holding the other IVs constant (because you can have many IVs, if you have a very large sample size). (college psyc prof)Why do we only study one independent variable at a time?
That's right. If you had two independent variables in an experiment, you would not know whether the difference was due to one, the other, or a bit of both. For example, imagine you were testing the effectiveness of an experimental drug and you gave someone two different drugs to try. How would you know which helped (or which gave a negative reaction)? You need to have just one independent variable.Why do we only study one independent variable at a time?
because you havent gotten to multi-variable calculus yet maybe? (which is Calc. 3)

When graphing, is time the independent variable or the dependent variable?
In other words, when does time go on the x-axis and when does time go on the y-axis? I heard that time is usually the independent variable, but are there exceptions to this rule? When would it be the other way around?When graphing, is time the independent variable or the dependent variable?
Time is generally the independent variable hence goes on the x-axis. Considering a speed-time or distance-time graph time goes on the x-axis. However, I have seen instances where time went on the y-axis i.e. it was the dependent variable. During one of my Bio practicals, we were investigating the effect of pH on enzymatic activity. We had to find out the time taken for a protein film to disappear, for certain pH values. Hence pH here was independent and time dependent.
We usually choose a dependent variable that is in some way controlled by the independent variable. Since time (unfortunately) answers to nothing and no one, there are rarely situations that would call for it to be the dependent variable. But I can think of a few.
Suppose we are roasting a turkey. How long should it be left in the oven? That depends on how much it weighs. It would be possible to construct a graph in which roasting time is a function of weight.
Now suppose you are staying at a resort. You like it, but how long can you stay? That depends on how much money you have.When graphing, is time the independent variable or the dependent variable?
most likely x-axis. its independent because time doesnt change with some characteristic, it is constant. however some other value may change over the course of time.When graphing, is time the independent variable or the dependent variable?
Depends on what you are graphing. If it is velocity, time is on the x axis.

What's the independent and dependent variable in this short study?
The experiment is called, "Be a Juror"
Purpose: This study regarding the effect of eyewitness testimony can be used to generate a discussion regarding the influence on juries of such testimony
Information: The computer randomly assigns each participant to one of three different scenarios, in which the participant learns details of a crime. In the first scenario, the defendant provides testimony and argues he is not guilty. The second scenario is similar but also includes a statement that a witness saw the defendant commit the crime. In the third and final scenario, an attorney indicates that the witness was not wearing his glasses, thus his testimony may have been false.
Design
Participants are in one of three treatment conditions (a) no eyewitness, (b) discredited eyewitness, and (c) unrefuted eyewitness. Participants in this study rate their belief about the defendant's guilt. The rating scale ranges from a 1 (definitely not guilty) to a 7 (definitely guilty).
MY QUESTIONS:
1. What is the independent variable?
2. What is the dependent variable?
Thanks a lot!!!!!What's the independent and dependent variable in this short study?
The independent variable is the one which represents the three conditions. The participants then use the choice of those three conditions to evaluate on a scale of 1 - 7. So the assignment on the scale of 1-7 is dependent upon the choice of the three conditions.
Although this was not necessary for my answer the fact that the computer *****randomly***** assigns one of the three conditions means that the variable cannot be dependent. Random does not allow for dependence.
Summarizing

im doing an experiment in school to see the flexibility of a turkey and chicken bone after being put in 3 different liquids for 24 hrs (soda, orange juice, and coffee) so whats the dependent and independent variable?What exactly is a dependent and independent variable in an experiment?
Independent variable: is a variable that you can manipulate
Dependent variable: is a variable that is measured
so for example the independent variable would be the time or the liquids because you are in control of them while the dependant variable would be what would happen to the bone.
I think thats right. if not im sure someone else will explain it better.
u stink
The different variables are the controlled, independent, and dependent responding variables. The controlled variables are what you keep the same in the experiment. The independent variables are what you change on purpose in order to find the results. The dependent variable is what the results are based on the independent variables.What exactly is a dependent and independent variable in an experiment?
make sure to have a control! (either the bones in water or in nothing at all)
independent variable is what you can change-- this is the liquid in your ex.
dependent variable is what you measure-- in this case the flexibility
If you want something cool to happen to the bones, but some in vinegar. Seriously, it will make them bend like rubber.
"In an experiment, the independent variable is the variable that is varied or manipulated by the researcher, and the dependent variable is the response that is measured."
Based on this, the liquids are the independent variables, and the dependent variable is the flexibility.
The dependent variable is turkey flexibility and the independent variable is the type of liquid that you are soaking the turkey in.
A dependent variable relies on the information and data given by the independent variable. Time would be the independent variable and flexibility would be the dependent variable.
the independent variable is the thing that will not change during the experiement (time)
depends are the things that change depending on the indepent (the bones)
flexability after liquid would be dependent and the type of liquid would be independent.
independent variable is type of liquid

Can you help me find a hypothesis and a independent variable?
i'm going to do this science fair project where im going to give different types of energy drinks(such as monster,red bull etc..) to people and determine which of the energy drinks worked better and how it affected the people.but i need a independent variable and hypothesis.what do you think would be a good hypothesis and independent variable?Can you help me find a hypothesis and a independent variable?
The independant variable (the thing you control) is the type of drink given.
The constants might include time of day, and quantity.
I'd have everybody record their bedtimes. Then, ask them each to drink a fixed quantity of water 1 hour before bedtime, each day for a week, and record how long it took them to settle down.
Then, next week, try drink #1 instead of water. Record when they went to sleep.
Week #3, try a different drink 1 hour before bed. Same quantity. Same time, different beverage.
Try a different beverage each week. If weeks would extend your experiment too far, choose days.
Hypothesis: Guess which beverage will keep people awake longest. The one with the most caffeine? The one with the most sugar? The one with the most ____?Can you help me find a hypothesis and a independent variable?
Simply stated, your independent variable is the type of drink. Your problem is going to be to find a hypothesis based on a measurable dependent variable (how do you measure their energy?) and control of other variable, like what they had for dinner last night, their intrinsic health condition, and so on. This is one reason (only one; there are lots of others) why scientists prefer working with cultured rats rather than real humans.
There are lots of possibilities for the dependent variable; once you've chosen it, then your hypothesis becomes something like: Energy drinks tend to increase muscle tone (dv) in humans. To do this for real you'd need some basis in statistics, which I don't assume you've had yet. You'd need to use it not just to analyze your results, but to determine how many people you need to form a sample size such that a single false result (due to some other factor, or just random error) doesn't lead you to a false conclusion. Most science fair projects are pretty limited to really objective observations, since sufficient statistics doesn't usually exist in high school curricula.Can you help me find a hypothesis and a independent variable?
The independent variable, or what factor you are changing, is the type of energy drink give to the people. The dependent variable, or what you are measuring, is the effectiveness of the energy drink. The hypothesis could be, "If a person is given an energy drink with more (some measurable ingredient based of the label on the back of the can), then the energy drink will be more effective in the energy obtained by the person.

What is the dependent/independent variable in this question?
In the first scenario, you, as a medical researcher, are interesting in whether a new cholesterol lowering medication has an unwanted side effect of changing blood pressure. You randomly sample 100 adult volunteers in your community. You give 50 of the volunteers a placebo and 50 of them the cholesterol lowering drug for a month and then read their blood pressure.
Would the independent variable be the group with the placebo pill and the dependent variable the group with the actual pill?What is the dependent/independent variable in this question?
no, you are not correct. What you listed are both under the independent variables :)
independent variable: type of pill - placebo pill vs. medication pill
dependent variable: level of blood pressure
independent variable is the thing that you, the researcher, purposely changes in order to see how it will effect the results. You purposely given one group a placebo and another group medication. So they both under the independent variable
dependent variable is the results, which has to be measurable in some way. Here, you can measure it by testing the person's blood pressure.What is the dependent/independent variable in this question?

What is a independent variable, dependent variable, and control group?
I am 14 years old so try and put it in a kid way please, i think independent variable is like the "experiment" like the main thing. But am still unsure of the rest, make it as easy and simple as possible tyWhat is a independent variable, dependent variable, and control group?
Independent Variable: what the experimenter uses or changes to produce results.
Dependent Variable: Measured changed due to independent variable.
Control Group is what stayed the same.
Ex: You are testing the growth of flowers. You believes that flowers with fertilizer grows taller. You water the flowers equally each day. The flowers receives an equal amout of sunlight each day.
Independent V: Fertilizer(It's changing the growth).
Dependent Variable: The Height of the flowers(whats being measured)
Control Group: Water %26amp; Sunlight. (What stays the same)What is a independent variable, dependent variable, and control group?
In in an experiment you change the independent variable.
Say, you want to see if a tennis ball with a big hole or a small hole floats better.
It's the thing that is never the same.
It's indepent, it's crazy and on it's own. =P
The dependent is the time it takes to sink, it's the part of the experiment that you can't change directly.
and the control would be a tennis ball that you didn't change at all, a normal one.

Do high school students do better grade-wise if they are on a sports team?
Any help would be great.What is the dependent and independent variable?
Dependent- grades
independent-sports team
Remember independent is the one that you can change
Dependent-is the result you get from the change
The dependent variable is the high school students doing better and the independent variable is the sports team deal...What is the dependent and independent variable?
the grades are the dependent variable (because you are trying to find out whether the grade DEPENDS on being on a sports team.
The spots team is thus the independent variable.
.What is the dependent and independent variable?
Well that graph would be "number of teams" and "% grade" is suppose. The number of teams is the one that decides the %, so its independent. The %grade is affected by the #of teams and is therefore dependent.
the variables you are measuring are 1)grades and 2) are they on a sports team?
The only thing you can really rely upon, independant of what their grades are, is are they on a sports team. Then their grades will vary DEPENDING UPON that.

What is an independent variable and dependent variable?
My hypothesis is that Girls are more helpful than boys.
What would the independent and dependent variable be?What is an independent variable and dependent variable?
so in other words your hypothesis would be that gender influences helpfulness.
so your independent variable would be gender
your dependent variable would be helpfulness.
good luck!
Mathematically speaking, the independent variable is the "manipulated" variable and the dependent variable changes in response to the independent variable.
If you were to graph the results, the independent variable would be plotted on the x axisand the dependent variable would be plotted on the y axis.
In your scenario, you don't have a variable that you can "control" because your statement is more of a theory ... You could create a "set-up" situation where someone needs help, then have an equal number of boys and girls encounter the scene and see who stops to help. If more girls stop to help (compared to boys) you would be able to defend your theory. Make sure you use as large a number of boys and girls as possible, it will make your results more "scientifically sound". If you only used a few girls and boys your results could be challenged or considered coincidence.
An example of an experiment that independent and dependent variables would be the effect of increased caloric intake on weight gain. Your independent (or x) variable would be varying caloric intakes (measured in calories). The dependent (or y) variable would be the weight gain associated with each caloric intake (measured in pounds).
Make sense? I hope I helped. Good luck.What is an independent variable and dependent variable?
its the terms to be on which axis on a graph.
the first on goes on the bottom, and the other one goes on the top.
the the dependent variable depends on the dependent variable.
Does that make sense?What is an independent variable and dependent variable?
An independent variable doesn't depend on another. And a dependent variable does.
For example:
y = 5x + 3
Y is a dependent variable because it increases when x increases.
X is independent.
Hope this helped.

What would be the independent variable in this experiment?
I want to do an experiment on weather highlighting the word or simply looking at the word/terms which one would a person better memorize...what would have a better effect of the memory?
So what would be the independent variable?
Thanks!What would be the independent variable in this experiment? Psychology research?
If you were to artificially control the weather in some way (e.g., you, as the researcher, control the temperature of the room in which your participants perform their memory task) temperature would be your independent variable.
However, if you are simply planning to compare memory on day one (say a day with thunderstorms) to day two (say a sunny day), you are doing CORRELATIONAL - not experimental - research. In such a case, you have no independent variable.

Would this be my independent variable for my experiment?
My problem is to find out if the color of a wax candle affects the time it takes to burn.
The independent variable is the color and size of the candles.
The dependent variable is the time/rate the candles melt at.
Also, please tell me if my dependent variable is correct.Would this be my independent variable for my experiment?
yes, you are right on. the dependent variable is the one that varies as you change the independent variable. In this case, you are changing the color wax being melted, and measuring if the rate changes. the rate is dependent on the color.

I just answered this but again.
These words are different in science than in math although they have the same idea they are not the same.
1. Control Variable..are those variables that are not changed throughout the trials in an experiment because the experimenter is not interested in the effect of that variable being changed for that particular experiment, for a scientific experiment, the control variable never changes.
2. Variable... is a symbolic number, letter which holds a certain value, the variable often represents the unknown
3.Independent variable... is the variable which can be manipulated. The independent variable is able to stand on its own.
3. Dependent Variable... Is the uncertain variable, and its outcome relies on the independent variables reaction.
It is obvious how they are diffrent in that they each don't have anything to do with the other, aside from independent and dependent.

If I am to develop a Regression Model to predict the SELLING PRICE based upon the SQUARE FOOTAGE. Which is the Independent Variable and which is the Dependent Variable?What is the dependent and the independent variable?
You rely on your parents to give you food, shelter, love, etc - so you are dependent on them. In the same way, the dependent variable is the one that relies on something else.
In your problem, the selling price is based on, or relies on the square footage - it changes as the square footage changes. So the selling price is the dependent variable, and the square footage must be the independent variable (it doesn't rely on anything).
Hope this makes it easier to understand!What is the dependent and the independent variable?

Independent variables answer the question "What do I change"
Dependent variables answer the question "What do I observe"
Controlled variables answer the question "What do I keep the same"
A bit more detail into would be:
A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable. In a scientific experiment, you cannot have a dependent variable without an independent variable
%26amp;%26amp;%26amp;
An independent variable is a factor that can be varied or manipulated in an experiment (e.g. time, temperature, concentration, etc). It is usually what will affect the dependent variable

In a scientific experiment which is the independent and dependent variable?
Based on a quote from a scientific research study:
"among postmenopausal women, the lower the overnight production of melatonin - a brain hormone secreted at night, esp. during darkness- the higher the incidence of breast cancer"
which is the dependent variable and which is the independent variable. why?In a scientific experiment which is the independent and dependent variable?
The independent variable is the variable that you change (the amount of melatonin). The dependent variable is the variable that changes in response to the independent variable (incidence of breast cancer). The dependent variable DEPENDS upon the value of the independent variable.In a scientific experiment which is the independent and dependent variable?
The answer depends on exactly how the researchers designed the experiment. Certainly one independent variable is "Postmenopausal Women", or more likely the menopausal status of women chosen for the research (the other group being "Premenopausal Women"). If the researchers further divided the women into "High Melatonin Producers" and "Low Melatonin Produces" that would add a secondary level of independent variables to both groups of women. If that is the case, the presence or absence of breast cancer would be the dependent variable which, of course, is expressed as nominal or catagorical level data.
The easiest way to keep the independent and dependent variables apart is to note which one generates the data that the researcher is recording. Mind the "D's"; Dependent variables produce Data.beauty

Find the independent and dependent variable and confounding variables in this example?
Professor Ziti has confirmed the effectiveness of an attention enhancement pill manufactured in his lab. Dr. Ziti initially tested students using the Wechsler Attention Scale. Following this initial testing, the students were given the Ziti attention enhancement pill for three days. On the fourth day, Dr. Ziti tested the students again. Students performed better on the second testing, thus proving the effectiveness of the attention enhancement pill.

That depends on what you're trying to show. If they idea is that plants generate oxygen, then you have to look up how much oxygen a plant of the size of the ones in your biosphere produce. Then you need to know how much oxygen your fleas and snails need to survive. Then you might establish 3 levels of plants- the numbers that might produce enough oxygen with minimal investment in plants, a mid-level, and then a maximum number of plants that you're sure would produce enough oxygen, but take up more room in the biosphere than is desired. Then you measure how your animals do in each condition.

If an experiment has two independent variables how do you know which one effects the dependent variable?
If an experiment has two or more independent variable, how do you know which one effects the dependent variable?If an experiment has two independent variables how do you know which one effects the dependent variable?
You don't. When you do an experiment you have to set controls.
i.e. For one experiment hold indie variable 1 constant, and change indie variable 2. For another, hold variable 2 constant, and change 1. This should let you know if only one of the variables is affecting your dependent variable.

Spirituality speaking, what is the independent variable in this experiment?
This is just an example, but if you were to preform an experiment to see if there is a correlation between leg length and running speed, what is the independent variable? Normally it's the variable that is manipulated, but in this case, none of the variables are manipulated.Spirituality speaking, what is the independent variable in this experiment?
leg length
and yes it can be manipulated. The researcher can pick specific individuals based on their leg lengths (individuals with 20" leg length, individuals with 30'' leg length, individuals with 40'' leg length). Instead of using the word manipulated, think of it as a variable in which the researcher changes on purpose.
In an experiment, some variable or variables are manipulated. An experiment is only one type of study. In a study such as you described, the two variables would be statistically analyzed to determine the correlation between the two, and neither would be designated as independent.Spirituality speaking, what is the independent variable in this experiment?
leg length, lung capacity, conditioning, genetics, location, wind speed, type of shoe, track conditions, body mass, etc. etc.Spirituality speaking, what is the independent variable in this experiment?
Leg length would be the independent variable. Running speed would be the dependent.
Leg length.
The running speed would be the dependent or "response" variable.
Peace.

How do i figure out the difference between the dependent variable and the independent variable in an expiremen?
The purpose of the expiremnt was to see which surface a volleyball rolled faster on, wood, cememnt, or concrete. I recorded the time of the ball on each surface at 10 inches, 20 inches, and then 30 inches. Is the time the dependent variable? or is the time the independent variable?How do i figure out the difference between the dependent variable and the independent variable in an expiremen?
The independent variable is the one that you change, so the surface. The dependent variable is the one that's affected by the changing of the independent variable, so it's the time.How do i figure out the difference between the dependent variable and the independent variable in an expiremen?
The independent variable is what you change. The dependent variable is what changes as a result of the changed independent variable. Thus, the time is the dependent variable and the surface is the independent variable.How do i figure out the difference between the dependent variable and the independent variable in an expiremen?

What are the independent, dependent, and control variable for my project?
I have a project/powerpoint due tomorrow and I have to know my control variable, independent variable, and my dependent variable. But I'm not completely sure on what they are.
The project is "What Temperature is Best for Helium Balloons?"
I'm using room temperature, cold temperature, and warm temperature as my choices. So if you have any ideas, that'd be a lot of help. Thanks!What are the independent, dependent, and control variable for my project?
The independent variable is what is being changed or manipulated. So the three balloon temperatures: room, cold and warm.
The dependent variable is the outcome. You haven't given a lot of info so I'm not sure what you are actually looking at, but it is what is affected by the changes in your independent variable.
The control variable would be room temperature, since you're comparing what happens when you use cold and warm temperature to a room temperature balloon.What are the independent, dependent, and control variable for my project?
independent: temperature
dependent: amount of helium in balloon (measuring the diameter of the balloon)
controls: use same type of balloon filled with the same amount of helium
control group: one at room temp
experimental group: ones at cold and warm tempsWhat are the independent, dependent, and control variable for my project?
Independent variable is ambient temperature. Control variable might be lift caused by buoyancy of the device. Dependent variable might be rate of climb due to lift.

What is the dependent and independent variable of this experiment?
Im doing an experiement on Fitness and Heart rate. Here is my question/hypothesis:
Does moderate excersize increase heart rate, if so, by how much? What is the dependent and independent variable?
(Thanks Emma)What is the dependent and independent variable of this experiment?
The independent variable is the variable that is being manipulated or changed.
The dependent variable is the thing you are measuring to see if the independent variable has had an effect on it.
So here you are measuring heart rate, and you want to know if exercise has an effect on heart rate, you want to know if the heart rate is "dependable" on exercise. So your independent variable is exercise. And the dependent variable is heart rate. Hope this helps!
The way to think about a question like this is "what is the cause; what is the resultant effect?"
The 'cause' is the 'independent variable', since this is what brings about the 'effect'. You can choose any value you like for the independent variable; the dependent variable simply 'does what it is told'! [Compare to a dependent child and its parent. ;-) ]
So you can see that the 'effect' is the dependent variable, since it depends on the 'cause' - the independent variable - to determine its value.
This concept of 'cause %26amp; effect' is at the heart of mathematics.
Glad to help.What is the dependent and independent variable of this experiment?
Independent: moderate exercise
Dependent: heart rate
a good way of identifying the variables is to just remember that the first variable in your problem is the independent variable and the second variable is the dependent.What is the dependent and independent variable of this experiment?
heart rate = dependent variable since it will increase or slow down based on amount of exercise
exercise = independent variable this will affect your heart rate

How do you decide which is the independent variable for a scatter plot?
I'm given two sets of data and i need to make a scatter plot and i have to decide which is the independent variable but don't know which one to put. one set is the carbon emisions for year 2000 for 30 countries, the other is the gross national income for year 2000 for them 30 countries. I'm also asked how i decided which was the independent variable. thanks.How do you decide which is the independent variable for a scatter plot?
It's more likely that changes in GNI will affect the carbon emissions, so GNI is the independent variable and carbon emissions is dependent (on GNI).
As GNI goes up people will be doing more things that produce carbon emissions, like driving and burning fossil fuels for electricity. Fairly simple to link cause and effect.
In reverse, it's not likely that carbon emissions would change without a change in GNI and it would involve a long and complicated set of circumstances for GNI to be altered by changes in carbon emissions.

What would be the independent variable in this science experiment?
I'm testing the effectiveness of salt in controlling bacterial growth in milk. I'm going to be using 2 diff brands of milk and different amounts of salt and then counting the number of bacterial colonies (in agar plates). Just wondering, what would be the independent variable in this experiment?
Is it the different amount of salt added?What would be the independent variable in this science experiment?
The independent variable should be the amount of salt added because it affects the dependent variable, that is the amount of bacterial growth in milk. Since the amount of milk is kept constant for the 2 brands, it is a controlled variable.
If the experiment is investigating the number of bacterial colonies for different brands of milk, the independent variable will then be the brand of milk, with the amount of salt used and the amount of milk used kept constant.
Good luck for your experiment! :DWhat would be the independent variable in this science experiment?
well you've got two variables and no control.. so its not going to work.
you are going to need (for example)
20ml X brand milk with no added salt
20ml X brand milk with 1gm salt
20ml X brand milk with 5gm salt
20ml Y brand milk with no added salt
20ml Y brand milk with 1gm salt
20ml Y brand milk with 5gm salt
so each of your two brand types of milk with no added salt are your control. and your variables are your milk brand and also the amount of salt.
alternatively you could just use one type of milk as it seems like the experiment is really based on the salts effectiveness rather than the brand of milk.makeup set

Does every experiment have to have an independent variable?
Im doing an experimant on electrolysis of water. But my experimant does not have an independent variable cause im not changing anything..? So is it required to have an independent variable.Does every experiment have to have an independent variable?
Experiments involve observing/measuring dependent variables, therefore there have to be independent variables. Even though you aren't changing something, it doesn't mean that something can't be changed. Is this really an experiment that you're doing or are you just trying to create something?
