Can you please explain how to calculate this on Excel? For each column

count, n = 10 10 10
mean , x i = 5.1 2.4 2.9
std. dev., si = 1.4 1.5 1.5
sample variances, si^2 = 2.1 2.267 2.322
total sum 51 24 29 104
grand mean , x = ni*xi/ni = 3.47
( x - x ) 2.668 1.138 0.321
SS(between)= SSB = n( x - x) = 26.678 11.378 3.211 TOTAL 41.267
SS(within ) = SSW = (n-1)s = 18.9 20.4 20.9 60.2
