A researcher is comparing 6 groups to test if they have the same means. There are 53 data values altogether. The degrees of freedom for the Between (dfB) and the degrees of freedom for the Within (dfW) are
A) dfB = 47, dfW = 52
B) dfB = 5, dfW = 47
C) dfB = 5, dfW = 52
D) dfB = 6, dfW = 52

The degrees of freedom for Between (dfB) is calculated as the number of groups minus 1, which is 6 - 1 = 5. The degrees of freedom for Within (dfW) is the total number of data values minus the number of groups, which is 53 - 6 = 47.
