Everything Up to Factorial ANOVA (two-way between-groups ANOVA) One of the surprising findings presented in the OKCupid article, "Awomen's advantage," was that women prefer to split the bill on the first date more than men. Imagine that we have recruited 20 male and 20 female undergraduates. We ask the participants to rate the likelihood, on a 5-point rating scale (1=never, 5=always), that they would want to split the bill on a first date. What statistical test could be used to determine if there was a significant difference in preference ratings between the two groups? a. z test b. single-sample t test c. paired-samples t test d. independent-samples t test e. one-way between-groups ANOVA f. one-way within-groups ANOVA g. two-way between-groups ANOVA
