The researcher is comparing two categorical variables (experiencing abuse and divorce status), which is best analyzed using a Chi-square test for independence. The degrees of freedom for a Chi-square test for independence are calculated as (rows - 1) * (columns - 1), which in this case is (2-1)*(2-1) = 1.
