Quizplus · Accepted Answer

This study represents a within-subjects factorial design because it is examining the effects of two independent variables (color and size of containers) on the same dependent variable (people's tendency to buy a certain brand of cereal) within the same group of subjects. The fact that all combinations of color and size are being tested further supports the within-subjects design.
