Question

Quizplus · Accepted Answer

The degrees of freedom for analyzing data cross-classified in a contingency table is computed by taking the product of the degrees of freedom for each dimension of the table. For a contingency table with r rows and c columns, the degrees of freedom are calculated by (r-1) x (c-1). This is because each value in the contingency table is dependent on the other values in the same row and column, leaving r-1 x c-1 degrees of freedom for analysis once the row and column totals are known. Therefore, the best choice is D.
