In Chapter 6 (Exercise 6.38) we examined data presented by Hout et al. on the sexual satisfaction of married couples. We did that by setting up a contingency table and computing on that table. We looked at those data again in a different way in Exercise 7.19, where we ran a t test comparing the means. Instead of asking subjects to rate their statement “Sex is fun for me and my partner” as “Never, Fairly Often, Very Often, or Almost Always,” we converted their categorical responses to a four-point scale from 1 5 “Never” to 4 5 “Almost Always.”

a. How does the “scale of measurement” issue relate to this analysis?

b. Even setting aside the fact that this exercise and Exercise 6.37 use different statistical tests, the two exercises are asking quite different questions of the data. What are those different questions?

c. What might you do if 15 wives refused to answer the question, although their husbands did, and 8 husbands refused to answer the question when their wives did?

d. How comfortable are you with the t test analysis, and what might you do instead?
