Number of treatment, k = 3
Total sample Size, N = 18
df(between) = k-1 = 2
df(within) = N-k = 15
df(total) = N-1 = 17
Answer: dfwn = 15; dfbn = 2
----------
Q13:
SS(between) = (Sum1)²/n1 + (Sum2)²/n2 + (Sum3)²/n3 - (Grand Sum)²/ N = 27
SS(within) = SS1 + SS2 + SS3 = 15
SS(total) = SS(between) + SS(within) = 42
MS(between) = SS(between)/df(between) = 13.5
MS(within) = SS(within)/df(within) = 1
Answer: MSbn = 13.5; MSwn = 1
----------
Q14:
F = MS(between)/MS(within) = 13.50
