QUESTION 5

1. Group A has three scores, 34, 24, 21. Group B has three scores, 48, 34, 30. Group C has three scores, 22, 40, 26. Calculate SS total (the total sums of squares). Round to two digits.

Answer 1

1)

F-value= MS effect /MS error

MS effect = F-value*MS error = 2.1 * 86 = 180.6

SS effect = MS effect*df effect = 180.6 * 5 = 903.00

2)

SSerror =SStotal - SS effect = 89 -36 = 53

3)

	A	B	C
count, ni =	3	3	3
mean , x̅ i =	36.67	24.00	34.00
std. dev., si =	4.04	20.81	12.49
sample variances, si^2 =	16.333	433.000	156.000		total
SS(within ) = SSW = Σ(n-1)s² =	32.66666667	866.00	312		1210.667

so, SS error = Σ(n-1)s² = 1210.7
