You will submit one Word document for this assignment, In the first part, you will provide short answers to the following questions (250 words or less). Name the file in the following format: lastnamefirstinitialPSY7107-9.doc (example: smithbPSY7107-9.doc).
Begin by downloading the following SPSS datasets:
• Activity 6a.sav (found on the “additional resources” page)
• Activity 6b.sav (file you created in Week 8)
• Activity 6c.sav (found on the “additional resources” page)
Part A. Questions about non-parametric procedures
What are the most common reasons you would select a non-parametric test over the parametric alternative?
Discuss the issue of statistical power in non-parametric tests (as compared to their parametric counterparts). Which type tends to be more powerful? Why?
For each of the following parametric tests, identify the appropriate non-parametric counterpart:
Dependent t test
Independent samples t test
Repeated measures ANOVA (one-variable)
One-way ANOVA (independent)
Pearson Correlation
Part B. SPSS Assignment
In this part of the assignment, you will perform the non-parametric version of the tests you used previously. In each case, assume that you opted to use the non-parametric equivalent rather than the parametric test. Using the data files from earlier activities, complete the following tests and paste your results into the assignment Word document:
Activity 6A: non-parametric version of the dependent t test
Activity 6B: non-parametric version of the independent t test
Activity 6C: non-parametric version of the single factor ANOVA
