I don’t know the experiment you did but I can tell you the definitions and common variable types.
Independent variable: a variable (often denoted by x ) whose variation does not depend on that of another. Two examples of common independent variables are age and time.
Dependent variable: a variable (often denoted by y ) whose value depends on that of another. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment.
Hope this helps :)
