The following data summarize the results from an independent-measures study comparing three treatment conditions.

I II III

n = 6 n = 6 n = 6

M =1 M = 5 M = 6 N = 18

T = 6 T = 30 T = 36 G = 72

SS = 30 SS =35 SS = 40 ?X2(x square) = 477

a. Use an ANOVA with α = .05 to determine whether there are any significant differences among the three treatment means.

b. Calculate ?2 (? square) to measure the effect size for this study.

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