Learning Objectives
After reading this chapter, you should be able to:
1. Identify the analysis of variance test and when it is used for tests of a single factor.
2. Identify each source of variation in a one-way between-subjects ANOVA and a one-way within-subjects ANOVA.
3. Calculate the degrees of freedom and locate critical values for a one-way between-subjects ANOVA and a one-way within-subjects ANOVA.
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.
8. Delineate the power of between-subjects and within-subjects designs for the one-way ANOVAs.
9. Summarize the results of the one-way between-subjects ANOVA and the one-way within-subjects ANOVA in APA format.
