If you are asking what a dependent variable is, here is your answer:
A dependent variable is a variable which would be the output of the experiment. The value of the dependent variable depends on the value of the independent variable.
If you are asking what a dependent variable does, here is your answer:
A dependent variable shows you the output of the experiment. It shows you the independent variable's function. If you have learned that in Math, you should understand.

In some mathematical situations you find that some variables depend on others. Those that do are called the dependant variables. So for y=2x , the value of y depends on what you choose for x , so y is the independent variable, and x is the independent variable. But if you were to ask the question "what value of x would make y=2" you would rehash the equation to be x=y/2, and you would then view x as the dependant variable and y as the independent variable. In all cases, the "answer" is the dependent variable, and the "input" is the independent variable.
A dependent variable is a mathematical variable whose value is determined by the value assumed by an independent variable.
The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
It means that your observation of the subject in question has not been constant or to plan.
The dependent variable.
The dependent variable is the variable that depends on the independent variable.
the test variable is the independent variable.
