Quizplus · Accepted Answer

The appropriate chi-square test for analyzing association between two categorical variables (coupon redemption and gender) is the test for independence. Goodness-of-fit test is used to analyze if the observed frequencies fit a hypothesized distribution, while homogeneity test is used to analyze if the distribution of frequencies of a categorical variable is the same across different groups. Normal distribution is not applicable in this situation, and Gosset's t is a test for comparing means of two independent samples.
