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 and interpret Tukey’s HSD post hoc test and identify the most powerful post hoc test alternatives.

7. Compute and interpret 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.
