Answer Both questions 1. In general, when should you use non-parametric vs. parametric tests? 2. Specifically, what are the parametric equivalents of the Mann-Whitney, Wilcoxon rank-sum & signed-rank, Kruskal-Wallis, and Friedman's tests? what type of variables or research design would call for each of these tests (i.e. how do know which test to use)?

6. Parametric tests usually have more statistical power than non-parametric tests. True or False 5. A post hoc test does not need to be performed when an ANOVA produces a statistically significant F value. True or False 4. In the case of a hypothesis t test, population mean is known. True or False

When should we use a non-parametric test (or a distribution-free test)?

An advantage of non-parametric tests includes: a. Good power compared to parametric tests b. Set up to test hypotheses and estimate effect size c. Very few assumptions for the distribution of the data d. Allows for analysis of large continuous scale data sets
