She wants some estimate of the degree of relationship between a person's lateness and his or her exam scores in her class. Which statistic should she use? a. Z-test b. One Sample t-test c. Independent groups t-test d. Dependent groups t-test e. One Factor ANOVA f. Two factor ANOVA g. t-test for r > 0 h. Chi-square test i. Phi Coefficient j. Cramer’s Phi k. Point Biserial r L.
