Quizplus · Accepted Answer

The df value for the chi-square test for independence is calculated using the formula df = (R-1)(C-1), where R is the number of rows and C is the number of columns in the contingency table. This formula reflects the number of degrees of freedom that are lost due to the constraints of the independence assumption used in the chi-square test. Choosing option D will give the correct answer.
