Detailed Case,Theory & Numeric Problems-20 Questions - Sample Size, Effect Size, Power Analysis, Hypothesis & Non-Parametric Tests (Ex 13, JUS 302 Ch 9, t test, G*Power, ANOVA, SPSS, etc)

Main Task: Application � Non-Parametric Tests You will submit one Word document for this activity. In the first part your activity document, provide short answers to the following questions (250 words or less).  Part A. Questions about non-parametric procedures 1. What are the most common reasons you would select a non-parametric test over the parametric alternative?  2. Discuss the issue of statistical power in non-parametric tests (as compared to their parametric counterparts). Which type tends to be more powerful? Why?  3. For each of the following parametric tests, identify the appropriate non-parametric counterpart:

a. Dependent t test

b. Independent samples t test

c. Repeated measures ANOVA (one-variable)

d. One-way ANOVA (independent)

e. Pearson Correlation

Part B. SPSS Activity In this part of the Activity you will perform the non-parametric version of the tests you used in Week 4. 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 a Word document: 1. Week 4 Activity 6, Part A: non-parametric version of the dependent t test 2. Week 4 Activity6, Part B: non-parametric version of the independent t test 3. Week 4 Activity6, Part C: non-parametric version of the single factor ANOVA
