Hout, Duncan, and Sobel (1987) reported data on the relative sexual satisfaction of married couples. They asked each member of 91 married couples to rate the degree to which they agreed with “Sex is fun for me and my partner” on a four-point scale ranging from

“never or occasionally” to “almost always.” The data appear below:

Wife’s Rating Husband’s Fairly Very Almost Rating Never Often Often Always Total Never 7 7 2 3 19 Fairly Often 2 8 3 7 20 Very Often 1 5 4 9 19 Almost Always 2 8 9 14 33 Total 12 28 18 33 91

(a) What hypothesis would you like to test with these data?

(b) Use Pearson’s chi-square to test your hypothesis. What would you conclude?

(c) Finally, what if you combined the Never and Fairly Often categories and the Very Often and Almost Always categories? Would the results be clearer, and under what conditions might this make sense?
