Quizplus · Accepted Answer

The group of preschool children who got to play with Ryan is the experimental group because they are the ones who receive the treatment of adult play. The comparison group across town would be the control group, as they do not receive the treatment. The pretest and posttest refer to measurements taken before and after the experiment, and the independent variable is the variable being manipulated (in this case, adult play).
