Some would object that the data in Exercise 13.1 are clearly discrete, if not ordinal, as defined

in Chapter 2, and that it is inappropriate to run a t test on them. Can you think what might

be a counterargument? (This is not an easy question, and I really asked it mostly to make the

point that there could be controversy here.)

Exercise 13.1

Hout, Duncan, and Sobel (1987) reported 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 (I know it’s a lot of data, but it’s an interesting

question, and the data can always be downloaded from the book’s website.):

Start out by running a matched-sample t test on these data. Why is a matched-sample test
appropriate?
