Quizplus · Accepted Answer

Sasha's experimental approach involves participants serving as their own control group, meaning they will take part in every condition of the study. This is a characteristic of a repeated measures design. Therefore, the correct answer is (D) repeated measures design. The other options are not applicable to Sasha's experimental approach. A one-shot case study involves measuring a single group at only one point in time, a simple random design involves randomly assigning participants to different groups, and an independent groups design involves comparing two or more separate groups.
