Q1. The following data are coming from a study in which students were classified into three groups based on the number of courses they failed in the last academic year. The students then completed a self-esteem questionnaire and rated their level of agreement with each item, and the total score was calculated for each student.

A. Use an analysis of variance with a = 0.05 to determine
whether these data indicate any significant mean
differences among the conditions (make sure to specify
all 4 steps of hypothesis testing).
B. Compute n? (eta squared), the percentage of variance
accounted for by the conditions.
C. Compute Tukey's HSD to determine exactly which
conditions are significantly different.
D. Write a sentence demonstrating how a research report
would present the results of the hypothesis test and the
measure of effect size.
Q2. The following summary table presents the results from a
repeated-measures ANOVA comparing three treatment
conditions with a sample ofn 11 subjects. Fill in the missing
values in the table (make sure to show all calculations. [10
