**PsyDAG**, Sunday, January 27, 2013 at 11:44ama. 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

b. Z = (score-mean)/SD

c. You can make up your own.

I'll let you do the calculations.
