Audrey examines students' learning of science principles from interactive games. She randomly assigns the fifth grade students in her study to a control condition with no play time, a timed play condition, or an unlimited time play condition. She also groups her students into either high or low ability groups. She measures her students with a knowledge pretest, a post-test, and a delayed post-test. Which of the following best represents Audrey's study design?
A) Pretest-posttest control group design
B) A 3 x 3 factorial design
C) A 3 x 2 factorial design
D) A 3 x 2 x 3 factorial design

Question

Quizplus · Accepted Answer

Audrey has two independent variables: play time (control, timed, unlimited) and ability group (high, low). These make up a 3 x 2 factorial design. The fact that she measures her students with a pretest, post-test, and delayed post-test indicate that this is a repeated measures design, but this information doesn't affect the choice of answer.
