What is the difference between dependent vairable and independent variable?

Yeah, so what's is the difference between an independent variable and a dependent variable?


Thankyou :)|||the dependent DEPENDS on the independent, so in a water boiling prac, the tempreture of water DEPENDS on how much time has passed, that means that the temperature is the dependent, because it depends on time. time would be the independent.|||Independent and dependent variables are related to one another. The Independent part is what you, the experimenter, changes or enacts in order to do your experiment. The dependent variable is what changes when the independent variable changes - the dependent variable depends on the outcome of the independent variable.





For instance: if you were measuring the growth rate of plants under full sunlight for 8 hours a day versus plants that only have 4 hours of full sunlight per day, the amount of time per day of full sunlight would be the independent variable - the variable that you control. The growth rate of the plants would be a dependent variable.





A dependent variable? Yes, there can be more than one dependent variable. In our example, for instance, the growth rate of the plants might be one dependent variable and the overall height of the plants might be another dependent variable. Both of these variables depend upon the independent variable.





When we talk about independent and dependent variables, we mentioned that you can have more than one dependent variable. Can you have more than one independent variable? No, there should be only one independent variable for any valid experiment (advanced forms of research do allow for more than one independent variable but unless you are doing this kind of research, you should probably stick to one.)|||Dependent variable - the thing that you are measuring [e.g time taken for a leaf to fall to the floor]


Independent variable - the thing you are changing [e.g distance to fall or size of leaf]
