**PsyDAG**, Tuesday, December 4, 2012 at 1:15pmI don't have a calculator with those keys, but here is what you can do.

Find 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

I'll let you do the calculations.
