Question: You will submit one Word document for this assignment, In the first part, you will provide short answers to the following questions.
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
