The degrees of freedom for a contingency table equal _________.
A) rc - 1
B) ( r - 1)( c - 1)
C) ( r - 1)( c )

Question

Quizplus · Accepted Answer

The degrees of freedom for a contingency table equal (r-1)(c-1) where r is the number of rows and c is the number of columns in the table. This formula takes into account the constraints of the row and column totals, resulting in (r-1) and (c-1) degrees of freedom, respectively. Therefore, the total degrees of freedom for the table is (r-1)(c-1).
