My mother always told me that the green tea is bad for your teeth. I attempted to prove her wrong by creating a controlled experiment. In it, I decided to get two people who volunteered as test subjects; person A was given a schedule where he would drink 3 green tea cups a day, person B was given a schedule where he would drink 3 cups of water every day. The result was that person A had his teeth darkened, person B's teeth remained the same color. What is the independent variable, the dependent variable and the controlled variable?
independent variable: green tea vs. water
dependent: teeth color
controlled: amount of liquid and how long...What is the independent variable, the dependent variable and the controlled variable?
Good expirement.
IV: Drink (Water, Green Tea)
DV: Color of Teeth
CV: The person same person (it doesnt apply to this one though), amount of liquid, time (how long you ran the expirement), there can be a lot.
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?".

International Relations ? - An example of a hypothesis in which you can specify the independent variable.....?
The full question(s) is:
Please list two forms which hypothesis make take.
Which are: x causes y
x is correlated with y.
Please give one example of a hypothesis in which you clearly specify which is (are) the independent variable(s) and which is the dependent variable.
I don't know how to answer that question, and what to use as an example. Please help! Remember this is international relations.International Relations ? - An example of a hypothesis in which you can specify the independent variable.....?

What is a independent variable and independent variable?
When testin a airsickness pill, what would be my dependent and independent variables? And how would I measure.What is a independent variable and independent variable?
the dose or time is independant %26amp; the reaction is independant
measure by....asking?? sickness isnt really something you measureWhat is a independent variable and independent variable?
Independent variable is the pill, dependent variable is outcome of taking pill. The way you should measure this is have an experimental group and a control group. The experimental group gets the pill before flying or whatever, and the control group doesn't. Record the outcome. However, you should try to use people for the experiment that you know get airsick. If not, you could possibly get a false positve or negative.What is a independent variable and independent variable?
The dependent variable is the condition of airsickness observed. The independent variables are the conditions you impose on the experiment, such as the pills or placebos you give to the people you are experimenting with. You measure the results of giving the pill to some people against the results of giving a placebo to others. That will determine whether the pill is effective.

What would the independent variable, dependent variable, and constant be for my science fair project?
My science fair project question is whether weather affects the growth of crystals.
I have the chemical powder, two rocks, two containers, and a mixing stick.
I'm like mentally challenged on finding all of the variables and costants.
Please help!
Thank you SO SO much!What would the independent variable, dependent variable, and constant be for my science fair project?
The independent variable is the conditions the crystals are growing in. It is called this because it does not depend on anything for it's value. You should have only one independent variable (you should only change one thing). The dependent variable is how the crystals turn out or how fast they grow. this is because it depends on the conditions it grows in. The constants would be everything you don't change which would be, the ingredients, the container. This is because they stay constant, they don't change.What would the independent variable, dependent variable, and constant be for my science fair project?
Crystal grown is the dependent variable
The two rocks are the "subjects"
The chemical powder and weather are the independent variables (the rocks presumably get exposed to the powder or the weather..)

What is the independent variable, dependent variable and type of study?
A pharmacologist is testing whether a new anti-anxiety medication, Moodcor, will cause people to gain weight. To test this, she gives 100 people moodcor for one month and 100 people a placebo drug (sugar pill). At the end of the month, she monitors any weight gain.What is the independent variable, dependent variable and type of study?
Independent Variable: The type of medication/pill.
Dependant Variable: Weight change.
Type of Study: No idea.maybelline express
Independent Variable: The type of medication/pill.
Dependant Variable: Weight change.
Type of Study: No idea.
How does the independent variable affect the dependent variable?
Im doing a science fair project, but i dont understand what this means.How does the independent variable affect the dependent variable?
It's simple really. The dependent variable 'depends' on the value the independent variable takes for its value.
Say you have: y = 3x - 2
This is the equation for a straight line right? Well, 'y' is the dep. variable, and 'x' is the indep. variable. So 'x' takes on any value you wish to give it. So if I assign a value of one (1) to x then y HAS to be 3*1 - 2 = 1.
So y = 1 ONLY when x has been given its value.
Understand?
Think of it like this:
When you go to a restaurant, you can ONLY get what the restaurant offers on its menu. You can't go to a hot dog joint and say "Hey....gimme a fillet mignon!".......right? Your meal DEPENDS on the menu.....your meal is 'dependent' upon the offerings of that restaurant...and the offerings of the restaurant are like the independent variable.
Does that help????How does the independent variable affect the dependent variable?

Independent and dependent variable question for biology?
A botanist is curious to know if a carnivorous plant grows better with a diet of live flies or dead flies. He puts in a terrarium with live flies, and he puts 3 other plants in a terrarium and feeds the plants dead flies by hand. He measures the height of the plants at the start and end of the experiment.
Independent variable:
Dependent variable:
Control:
Constants:Independent and dependent variable question for biology?
The independant variable is what you are looking for or what you dont have any control over. In this case its height.
The dependant variable is what you know or have control over, in this case, time.
The control is going to be what you are NOT testing for. In this case i think you can pick either one. Id pick the live flies as a control for dead flies as its closer to what happens in nature.
There really isnt a constant in this experiment but i guess you could say starting heightIndependent and dependent variable question for biology?
The independ. variable is actually defined as the treatment or condition under study. Therefore, in this case, it would be dead or alive flies. The depend. variable is the event or condition that is measured or observed %26amp; dependent on the independent variable. In this case, height.
this is biology!?
hahah. im learning this in algebra.!
