Revise the revised version of activity 7 submitted in the attached files. I am also submitting the original instructions as well as the needed files to complete the assignment. Note this work was previously submitted and received a score of 70 out of 100 hundred. Please revise the instructions as well as the comment made by the instructor on the revised version of the activity 7.

Activity 7: Apply Non-Parametric Tests
Activity Description
You will submit one Word document. In the first part your assignment 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 Assignment
In this part of the assignment 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 assignment, 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 Activity 6, Part B: non-parametric version of the independent t test
3. Week 4 Activity 6, Part C: non-parametric version of the single factor ANOVA
Your submittal should demonstrate thoughtful consideration of the ideas and concepts that are presented in the course and provide new thoughts and insights relating directly to this topic. Where applicable your submittal should reflect scholarly writing and current APA standards. Review APA Form and Style.
