Question

In a 2 x 2 table there are ( r - 1)( c - 1) degrees of freedom.

Quizplus · Accepted Answer

This statement is true. In a 2 x 2 table, there are two factors, each with two levels. Thus, there are (2-1)(2-1) = 1 degree of freedom for the row factor and 1 degree of freedom for the column factor, resulting in a total of (1)(1) = 1 degree of freedom.
