Given
DF between = 2
Df total = 29
Now calculate Df within
1) Df within = Df total - Df between
= 29 - 2
Df within = 27
SS within = 468
SS TOTAL = 818
2) NOW Calculate SS BETWEEN
SS Between = SS TOTAL - SS WITHIN
= 818 - 468
SS BETWEEN = 350
3) MS BETWEEN = SS BETWEEN / DF BETWEEN
= 350/2
MS BETWEEN = 175
4) MS WITHIN = SS WITHIN / DF WITHIN
= 468 / 27
MS WITHIN = 17.33
5) F = MS BETWEEN / MS WITHIN
= 175/17.33
F = 10.098
