1.      My one-way ANOVA has five groups. I have no focused hypotheses, only a general one that says there will be a significant between-groups effect. My omnibus F-test is significant at p = .02. What does this mean? Now what do I do?

2. The F ratio in my one-way ANOVA is 3.0. What is three times larger than what?

3.  I have a three-group study that uses a one-way ANOVA. (a) Is the omnibus F test a focused test or not? How many degrees of freedom does it have? (b) Suppose prior to data collection I have stated two hypotheses backed by previous studies: (1) group A will score higher than groups B and C combined, and (2) group B will score higher than group C. According to Rosnow and Rosenthal, what is my next step in the analysis?

4.   What is the difference between a between-subjects experiment and a within-subjects (repeated measures) experiment?

5.  Rosnow & Rosenthal. I conduct a 2-group study, my t is significant at .02, and my Cohen’s d is .55. You replicate my study, and you also get a Cohen’s d of .55. Was your t-test necessarily significant? If so, why must it be? If not, how could it not be?

6 .      In a meta-analysis, what is the file-drawer problem and is it something we need to take seriously?
