Detailed explanation-1: -The type of soda – diet or regular – is the independent variable. The level of blood sugar that you measure is the dependent variable – it changes depending on the type of soda.

Detailed explanation-2: -There are three main variables: independent variable, dependent variable and controlled variables.

Detailed explanation-3: -The independent variable (IV) in psychology is the characteristic of an experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.

Detailed explanation-4: -The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores since that is what is being measured.
