We examine the relationship between educational degree and church attendance. We selected a sample of 30 respondents from the International Social Science Program, noting their educational status (no degree, secondary degree, and university degree) and their level of church attendance (0=never, 1 = infrequently, 2 = two to three times per month or more). Set alpha = .01.
a. match the degree of freedom and its score
