(Runyon & Haber, 1991) In a recent study, Thornton (1977) explored the relationship of marital happiness to the frequency of sexual intercourse and to the frequency of arguments. Twenty-eight married couples volunteered to monitor their daily frequency of sexual intercourse and arguments for 35 consecutive days, and then they indicated their perceived marital happiness using an 11-point scale ranging from very unhappy (1) to perfectly happy (11). Thornton (1977) reported that the Pearson correlation between ratings of marital happiness and number of arguments was -0.74.

ANOVA only tells us that at least 2 means differ, but not which onesmust do Tukeys post-hoc test to compare multiple groups and determine which means differ. 14. Tukeys HSD is a post-test (multiple comparison procedure). One computes a Tukeys HSD when the null hypothesis has been rejected to determine which of the groups are significantly different from each other.
