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

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, MS_within
is the average of the three sample variances.

b. Calculate h²
to measure the effect size for this study.
