Question

Quizplus · Accepted Answer

Within-subjects ANOVA design involves measuring the same participants under different conditions, so the participants need to be observed multiple times (k) under each condition. Therefore, option B is the correct answer. Option A is incorrect because it suggests that only one observation is made per participant. Option C is incorrect because different participants are being observed in each group, which is not consistent with a within-subjects design. Option D is incorrect as it includes all the options, including the incorrect ones.
