Calculate SS, variance, and standard deviation for the following sample of n=9 scores:2,0,0,0,0,2,0,2,0.(Note: The computational formula for SS works best with these scores.)

I keep getting the wrong numbers. Thank You.

sum of squares

SS=E(x-u)squared in greek of course

I get:

u=.66666667

ss=8

v=1

sd=1

Note that I am using the formula for the estimate of the variance from a sample. So, I devide by n-1.
