If r is the number of rows and c is the number of columns, the total number of degrees of freedom in a two-way contingency table is given by
A) rc.
B) (r + 1)(c + 1).
C) (r - 1)(c - 1).
D) $ \frac{r - 1}{c - 1}$
E) $ \frac{r + 1}{c + 1}$

The total number of degrees of freedom in a two-way contingency table is calculated as (r - 1)(c - 1), where r is the number of rows and c is the number of columns. This formula accounts for the constraints that reduce the number of independent values in the table.

If R Is the Number of Rows and C Is r−1c−1 \frac{r - 1}{c - 1}c−1r−1​

If R Is the Number of Rows and C Is $\frac{r - 1}{c - 1}$
