-It would not be appropriate to use the Mann–Whitney U test when: a researcher is comparing two independent populations. the dependent variable is measured at the ordinal level. the assumptions for an independent-samples t test are not met. a researcher is comparing three or more groups on a normally distributed dependent variable. -Kia assesses people's levels of gratitude and stress that occur naturally to determine if a relationship exists between the two variables. Kia is using a(n): correlational design experimental...

Both chi-square and Pearson’s r provide information regarding the relationship between two variables. However, Pearson’s r is a more advanced statistic. Indicate why this is the case by listing two advantages that Pearson’s r has over the chi-square statistic. (3 points each) 1. 2.

Question #1 Explain what is meant by a positive relationship between two variables and a negative relationship between two variables. Describe examples of situations in which one would expect to find a positive relationship and when one would expect to find a negative relationship. Can one assign direction when both variables in a table are dichotomous?

You are testing the null hypothesis that there is no relationship between two variables, X and Y. From your sample of n = 22, you determine that SSR = 80 and SSE = 20. Construct the ANOVA table, test for model significance at a 0.05 level of significance and state your conclusion, and calculate the coefficient of determination and interpret its meaning.
