A researcher reports the results of an ANOVA for a repeated-measures study as "F(2, 12) = 7.84, p < .01." This study used a sample of n = 13 participants.

For a repeated-measures study comparing three treatment conditions with a sample of n = 4 participants, the participant totals (the P values) are 3, 6, 9, and 6, and the SS values within each treatment are SS₁ = 2, SS₂ = 2 and SS₃ = 6.What is the value for SS_error?

For a repeated-measures ANOVA, n = 5, k = 4, and error SS= 24.Therefore, MS_error = 2.

Based on the results of a repeated-measures ANOVA, a researcher reports F(4, 20) = 2.57, p > .05.For this ANOVA, the null hypothesis was rejected.

A researcher uses a repeated-measures ANOVA to test for mean differences among three treatment conditions using a sample of n = 10 participants.What are the df values for the F-ratio from this analysis?

The following table shows the results of a repeated-measures analysis of variance comparing two treatment conditions with a sample of n = 12 participants.Note that several values are missing in the table.What is the missing value for SS_total?

A repeated-measures study uses a sample of n = 10 participants to evaluate the mean differences among three treatment conditions.For this study, df_{between subjects} = 18.

A repeated-measures research study uses n = 8 subjects.If the within-treatment df for the ANOVA is 21, what is the value for the error df?
