**PSYC 815 Quiz: Non-Parametric and Repeated- Treatment Designs **

Covers the Textbook material from Module 7: Week 7.

- What is the independent variable?
- What is the dependent variable?
- What was the decision regarding the null hypothesis, H0: μ1 = μ2 = μ3?
- Before conducting comparisons of pairs of mean ranks, a Bonferroni adjustment is made to the alpha. What is the adjusted alpha?
- What were the results of the post hoc analysis comparing the pairs of mean ranks for differences?
- What is the independent variable in this second research problem?
- What is the dependent variable?
- What was the decision regarding the null hypothesis, H0: μ1 = μ2 = μ3?
- Before conducting comparisons of pairs of mean ranks, a Bonferroni adjustment is made to the alpha. What is the adjusted alpha?
- What were the results of the post hoc analysis comparing the pairs of mean ranks for differences?
- The non-parametric tests of Mann-Whitney U, Chi-square, and Wilcoxon require data to be either normally distributed, or have homogeneity of variance.
- The Mann-Whitney U is appropriately considered an alternative to the
- The Kruskal-Wallis is appropriately considered an alternative to the ________.
- Due to concerns regarding validity in nonparametric statistics as compared to parametric statistics, an alpha level of .01 should always be used when using nonparametric statistics.
- Using the information above, identify the dependent variable and its important characteristics, including the scale of measurement, needed to accurately design your study.
- Which nonparametric measure(s) would you use in this study, and why? Be sure to clearly connect and explain how your design accurately fits the characteristics of the statistic, or statistics, that you select.
- Using the information above, identify the independent variable and its important characteristics, including the scale of measurement, needed to accurately design your study.
- What ethical concerns and issues need to be addressed in this study? Consider both participant ethical considerations, as well as measurement/validity considerations. Note that this question does not require you to outline all the items needed to address ethical protocols such as informed consent. Instead, it is asking you to consider what ethical concerns might exist as you plan the study.
- in this scenario, the company is applying Scripture to what they do in the company operations. However, it is commonly understood that the Scriptures are applying more to individual “good works”, rather than as a guide for company policy. Yet, it is also appropriate to utilize scriptural principles in all aspects of life. Keep in mind that the company itself is not considered “a Christian company”, but that many of the leaders are Christians. Discuss the application and appropriateness of utilizing Scriptures such as these to driver influence company operations, especially as they relate to research efforts.
