**PsyDAG**, Thursday, May 5, 2011 at 11:17amFind 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

For two-tailed test, P = .05 for Z = 1.645.

I'll let you do the calculations.
