1. Why are you no longer directly comparing sample means?
2. How does using the F test - the analysis of variance (ANOVA) reduce your Type I error rate?
3. What is the difference between a within-groups and a between-groups variance?
4. If F is significant, why should you follow up with a post hoc test?
5. Why don't you use post hoc tests when F is not significant?
6. What are the assumptions of the F test?
7. How is the F test an extension of the t test?
8. Why are there two df measures with this test?
9. How do you interpret the findings of an ANOVA in terms of a variance measured
