The following data summarize the results from an independent-measures study comparing three treatment conditions. N = 18 G = 90 EX2 = 567 Treatment I II III n = 6 n = 6 n = 6 M = 4 M = 5 M = 6 T = 24 T = 30 T = 36 SS =30 SS =35 SS =40 a. Before you begin any calculations, predict how the change in the data should influence the outcome of the analysis. That is, how will the F-ratio and the value of ?2 for these data compare with the values obtained in problem 7? (Problem 7’s values are F(2,15) = 6.0 and ?2 = 0.444) b. Use an ANOVA with a = 0.05 to determine whether there are any significant differences among the three treatment means. (Does your answer agree with your prediction in part a?) Does your answer agree with your prediction in part a? c. Calculate n2 to measure the effect size for this study. Does your answer agree with your prediction in part a?
