The following data were obtained from a repeated-measures study comparing three treatment conditions. Use a repeated-measures ANOVA with α - .05 to determine whether there are significant mean differences among the three treatments. Compute η2, the percentage of variance accounted for by the mean differences, to measure the size of the treatments effects.
