For each problem, run the analysis in SPSS. Be sure to ask for descriptives and a plot of means.
Then TYPE the following additional information for each problem: (1) State the null and alternative hypotheses; (2) Paste in the matrices and graph. Also indicate your decision (retain Ho or reject Ho); (3) Write at least three sentences showing how the results would be written in the Results section of an APA paper. The first sentence reports the descriptive information (treatment means and standard deviations) and the second sentence reports the results of the ANOVA. Remember to include the value for eta squared if the statistic is significant. See my model or the "In the Literature" section in your statistics text. The third sentence should describe which follow-up comparisons were found to be significant.
