To calculate the sum of squares IV, we need to use the formula: IV = SS(total) - SS(within) where SS(total) = ÓX2 - ÓX/N = (92)2 - 92/5 = 8464 - 18.4 = 8445.6 SS(within) = Ós (_i² - ÓX2/N) = (1898 - 922/5) = 71.6 Therefore, IV = 8445.6 - 71.6 = 8374 So the answer is B, 71.33.

ÓX2 = 704 (ÓX)2 = 8464 ÓTj2 =3178

ÓX² = 704 (ÓX)²= 8464 ÓT_j²=3178
