The following data were obtained from a repeated measures study comparing three treatment conditions.

a. Use a repeated-measures ANOVA with Î± = .05 to determine whether there are significant mean differences among the three treatments.

b. Compute Î·2, the percentage of variance accounted for by the mean differences, to measure the size of the treatment effects.

c. Write a sentence demonstrating how a research report would present the results of the hypothesis test and the measure of effect size.
