Question

22. In which situation would it be inappropriate to use a nonparametric test? a. The sample size is small and the population distribution might be skewed. b. The dependent variable is scale. c. The dependent variable is nominal. d. The dependent variable is ordinal. 23. A chi-square test for independence is an appropriate statistical test to use when the study has: a. one nominal dependent variable. b. one scale independent variable. c. two nominal dependent variables. d. two scale independent variables. 24. In a study of simulated juror decision making. Braden-Maguire, Sigal, and Perrino (2005) investigated the type of verdict assigned by study participants after they read a 12-page summation of a case involving a battered woman who had shot and killed her husband. Of the 80 participants, 27 assigned a verdict of guilty, 40 a verdict of not guilty by reason of self-defense, and 13 a verdict of not guilty by reason of insanity. What type of chi- square test should the researchers use to determine whether the distribution of verdicts differed from what could have been expected by chance? a association b. dissociation C. goodness-of-fit d. independence 25. In a 2006 study, Gortmaker and Brown surveyed 80 lesbian and gay students at a large Midwestern state university to assess their experiences and their perceptions of the campus climate regarding lesbians and gays. One of the questions the researchers were interested in was whether a person's "outness" depended on his or her gender. All participants were classified as closeted or as out. What type of chi-square test should the researchers use to answer the question of whether outness varies with gender? a association b. dissociation c. goodness-of-fit d. independence 26. "The incidence of depression among college students is negatively correlated with the number of sunny days each year in the locale where they attend college." This statement means that: a. the chances of a college student being depressed tend to increase with fewer sunny days. b. a student attending college in a locale with very few sunny days will become depressed. c. the chances of a college student being depressed tend to increase as the number of sunny days increases.
