Summary

In this example, the post hoc tests did not reveal a difference in spending between customers who shopped biweekly and those who shopped more often. However, the estimated marginal means and profile plots revealed an interaction between the two factors, suggesting that male customers who shop once a week are more profitable than those who shop more often, while the pattern is reversed for female customers. The significance of this interaction effect was confirmed by the results of the ANOVA table.
