20. The following data summarize the results from an independent-measures study comparing three treatment conditions. M=2 M=3 M=4 n=10 T=20 n=10 T=40 In=10 T=30 s2=2.67 s²=2.00|s²=1.33 a. Use an ANOVA with a = .05 to determine whether there are any significant differences among the three treatment means. Note: Because the samples are all the same size, MSwithin is the average of the three sample variances. b. Calculate n to measure the effect siz for this study.
