Question

Quizplus · Accepted Answer

The number of degrees of freedom in a crosstab is calculated using the formula (r-1) x (c-1), where r is the number of rows and c is the number of columns. In this case, there are 2 rows (one for each sex) and 4 columns (one for each health category), so the number of degrees of freedom is (2-1) x (4-1) = 3. Therefore, the best choice is B.
