4.  Identify the assumptions for a one-way between-subjects ANOVA and a one-way within-subjects ANOVA.
 
5.  Follow the steps to compute a one-way between-subjects ANOVA and a one-way within-subjects ANOVA, and interpret the results.
 
6.  Compute Tukey’s HSD post hoc test and identify the most powerful post hoc test alternatives.
 
7.  Compute proportion of variance for the one-way between-subjects ANOVA and the one-way within-subjects ANOVA.
