When conducting a χ² test of independence with 8 groups in the first variable and 5 groups in the second variable, there are 28 degrees of freedom.

Question

Quizplus · Accepted Answer

The degrees of freedom for a chi-square test of independence is (r-1) * (c-1), where r is the number of rows and c is the number of columns. In this case, r = 8 and c = 5, so the degrees of freedom is (8-1) * (5-1) = 28.
