The independent variable is the variable that is manipulated by the experimenter in order to observe its effect on the dependent variable. The dependent variable is the variable that is being measured or observed as the outcome of the independent variable manipulation. Confounding variables and extraneous variables are factors that can affect the dependent variable but are not intentionally manipulated by the experimenter.
