Interpet the SPSS results of repeated measures ANOVA
A researcher was interested in determining whether comfort level with statistics changes across the course of a semester in an introductory statistics course. Data was collected from students on three different occasions (beginning, middle, and end of semester). Is there support for the conclusion that comfort level changes? The SPSS file* is “anova repeated measures assignment.sav” and the output file is “anova repeated measures results.doc”.
1. What might be a research question based on this data?
2. What is the null hypothesis?
3. Was the assumption of normality met? Was the assumption of sphericity met?
4. What was the value of the F statistic? Was it statistically significant based on alpha < 0.05? 5. What did the post-hoc test(s) indicate? 6. What would you conclude based on the results of the F test and the post-hoc test(s)?
