The following data were obtained from a repeated-measures study comparing three treatment conditions.
a. Use a repeated measures ANOVA with α=.05 to determine whether there are significant mean differences among the three treatments. (Hint: start by filling in the missing values on the table below). Be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all steps and all parts of all answers.
b. Compute n², the percentage of variance accounted for by the mean differences, to measure the size of the treatment effects. Be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all parts of all answers.
