Question

Quizplus · Accepted Answer

The formula to calculate degrees of freedom for a contingency table is:
(df) = (number of rows - 1) x (number of columns - 1)

Plugging in the values given in the question:
(df) = (6 - 1) x (3 - 1) 
(df) = 5 x 2 
(df) = 10

Therefore, the degrees of freedom for the contingency table is 10. The best choice is C.
