**PsyDAG**, Monday, March 28, 2011 at 12:10pmFind the mean first = sum of scores/number of scores

Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.

Standard deviation = square root of variance

SEm = SD/√(n-1)

I'll let you do the calculations.
