In an experimental design, the independent variable is the variable which is manipulated or selected by the experimenter to determine its relationship to an observed phenomenon (the dependent variable). In other words, the experiment will attempt to find evidence that the values of the independent variable determine the values of the dependent variable (which is what is being measured).
In experimental design, a dependent variable is a factor whose values in different treatment conditions are compared. That is, the experimenter is interested in determining if the value of the dependent variable varies when the values of another variable – the independent variable – are varied, and by how much.

In y = 3x
x is the independent variable, it can be anything
y is the dependent variable, it's value depends on x
Sure you could say I am going to make y=9 and find x but really you just made the equation x=y/3 and now y in the independent variable and x is the dependent

Oh wow. This is lucky. My class just did that.
Read the whole thing okay? I got it straight from my book...
manipulated variable - the one factor that a scientist changes during an experiment, also called the independent variable.
responding variable - the factor that changes as a result of changes to the manipulated variable in an experiment, also called the dependent variable.
Good luck with the homework, 'kay?

The independent variable is what you control. The dependent variable is the part that you can't control.
Think of it this way:
The height the plant grows depends on the amount of sun light you give it.
Try substituting your situation in that sentance. The varable that depends on the other is the dependent and the other is the independent.

an independent variable is what you are changing in the experiment and a deendent varible is waht changed because of the independent variable

Independent: on its own
Dependent: depends on the independent variable
Example: seeing how far a person travels over a certain amount of time.
Time is independent.
The distance traveled is dependent.
