Table 7.29 (page 212) summarized a study that reported the mean number of dates in the past three months.

For men, the mean was 9.7 for the more attractive and 9.9 for the less attractive. For women, the mean was 17.8 for the more attractive and 10.6 for the less attractive. Identify the response variable and the factors, and indicate whether these data appear to show interaction. Explain what you learn from a two-way ANOVA that you cannot learn from a one-way ANOVA.
