Explanation:
Detailed explanation-1: -An independent variable (IV) is a variable that is manipulated by a researcher to investigate whether it consequently brings change in another variable. This other variable, which is measured and predicted to be dependent upon the IV, is therefore named the dependent variable (DV).
Detailed explanation-2: -An independent variable is a factor that is manipulated in an experiment. The scientist decides whether or not subjects are exposed to the independent variable. The dependent variable is measured to determine if the changing of the independent variable had any effect.
