26. The following data were obtained from an independent- measures study comparing three treatment conditions. Treatment I n=6 M = 1 SS = 60 || n=6 M = 2 SS = 65 ||| n = 6 M = 6 SS = 40 N = 18 G = 54 EX² = 411 a. Calculate the sample variance for each of the three samples. b. Use an ANOVA with a = .05 to determine whether there are any significant differences among the three treatment means. (Note: In the ANOVA you should find that MSwithin is equal to the average of the three sample variances.)
