Calculate SS variance and standard deviation for the followi

Calculate SS, variance, and standard deviation for the following population of N=5 scores 10,4,8,5,8.

Mean = (10 + 4 + 8 + 5 + 8)/5

= 35/5

= 7

SS = (10-7)^2 + (4-7)^2 + ( 8-7)^2 + (5-7)^2 + (8-7)^2

= 9 + 9 + 1 + 4 + 1

= 24

Variance = 24/5 = 4.8

Std deviation = 4.8 = 2.19
