Hout, Duncan, and Sobel (1987) reported data on the relative sexual satisfaction of mar- ried 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:

 

 

Husband’s   Fairly Very Almost   Rating Never Often Often Always Total

Wife’s Rating

 

 

 

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?

 

 

I pointed out that we do not have a good measure of effect size to go with these tests, but that one approach would be to report the number of observations in one group that were smaller than the smallest observation in another group.
