For a contingency table test, the degrees of freedom depend on the number of rows and columns in the table. A contingency table with 4 rows and 15 degrees of freedom would have 6 columns. The formula for calculating degrees of freedom for a contingency table is (number of rows - 1) x (number of columns - 1). In this case, it would be (4-1) x (6-1) = 3 x 5 = 15.
