**PsyDAG**, Saturday, April 20, 2013 at 2:07pmFind 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

99% = mean ± 2.575 SD
