# What's an independent/dependant variable? watch

1. (Original post by Emerald777O)
In my textbook, it says "the variable that the researcher chooses to change or manipulate" then gives an example that if a psychologist wanted to research memory in school kids then the independent variable would be the age. I'm struggling to understand why they would change the age. That doesn't make sense to me. Can someone please dumb down this definition for me? Please.
Independent variable is what cause the dependent variable to change. Normally, when you take a graph the y=axis gives the dependent variable and x-axis gives the independent variable. But that is not always. Read the question in your exam papers when you do it then get an image to your mind to recognise y and x axis.

No same with maths.

If you change x (the independent variable), what happens to y(the variable dependent on the changing variable, x)?
No, i meant within psychology. I know the answer to that now. Thanks!
