Quizplus · Accepted Answer

An independent samples t-test is the best choice. This test is appropriate when comparing the means of two independent groups on a continuous variable, such as customer loyalty measured on a 5-point Likert scale. The bonus card group and non-bonus card group are independent because individuals can only belong to one group. ANOVA would be appropriate if there were more than two groups being compared. A paired-samples t-test would be appropriate if the study design involved comparing the same individuals before and after an intervention. A chi-square test would be appropriate if the study design involved comparing the frequency of categorical variables between groups.
