7. Assumptions underlying repeated-measures ANOVA Which of the following are assumptions underlying repeated-measures ANOVA? Check all that apply. The populations from which the samples were taken are normally distributed The population variances for each of the treatment groups (cells) differ.The population variances for each of the groups (cells) are equal. The values of the repeated variables are constant.
For either independent-measures or repeated-measures designs comparing two treatments, the mean difference can be evaluated with either at test or an ANOVA. The two tests are related by the equation F=12. The following data are from a repeated-measures study: Person Difference Scores 3 I 4 2 3 7 M = 4.00 T = 16 SS = 14 Treatment II 7 11 6 10 M 8.50 T-34 SS = 17 3 3 Mo 4.50 SS = 27.00 Use a repeated-measures t...

When assumptions are violated in repeated-measures ANOVA, a non-parametric test called Friedman’s ANOVA can be used in which situations? a. For any repeated-measures ANOVA design. b. When you have only one independent variable. c. When you have two or more independent variables. d. Never for repeated-measures ANOVA.
