The primary way that analysis of variance for repeated measures differs from that for an independent groups design is in the estimation of
A)between-group variation.
B)variability between means.
C)error variation.
D)systematic variation.

Question

Quizplus · Accepted Answer

In a repeated measures design, the same group of participants is measured multiple times, resulting in correlated scores. This correlation between scores needs to be taken into account when estimating error variation, as the variability between repeated measures within individuals is not independent. Therefore, the estimation of error variation in a repeated measures ANOVA is different from that in an independent groups design. However, the estimation of between-group variation and systematic variation remain the same in both designs.
