what is the difference between dependent and independent variables? Can you provide an example for me indicating which of the variables is dependent and which is independent?

• math -

dependant variable relies on something whereas an independant variable is not reliable on anything

Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).

For example:

(Time Spent Studying) causes a change in (Test Score) and it isn't possible that (Test Score) could cause a change in (Time Spent Studying).

We see that "Time Spent Studying" must be the independent variable and "Test Score" must be the dependent variable because the sentence doesn't make sense the other way around.

if I were to write and equation for this x being the study time and s being the score would this be correct

2x=s?
