A test for independence is applied to a contingency table with 3 rows and 5 columns for two nominal variables. The degrees of freedom for this test will be:
A) 20
B) 12
C) 8
D) 15

Degrees of freedom = (r  1)(c  1) ...where r = number of rows and c = number of columns.
I'll let you take it from there.posted by MathGuru
