Quizplus · Accepted Answer

Pretest-posttest experiments involve measuring the dependent variable both before and after the independent variable is manipulated. This allows researchers to account for any changes in the dependent variable that may have occurred due to maturation (i.e. natural developmental changes) rather than the manipulation of the independent variable. Therefore, pretest-posttest experiments have an advantage in separating the effects of the independent variable from maturation.
