D)R(C - 1)

Question

Quizplus · Accepted Answer

The formula for degrees of freedom in a chi-square test is (R-1)(C-1), where R is the number of rows and C is the number of columns in the contingency table. In a four-cell chi-square test, there is one row and one column, so the number of degrees of freedom is (1-1)(1-1) = 0. However, this is not a valid option for degrees of freedom, so we use the formula and get (1-1)(1-1) = 0. Therefore, the best choice is C.
