**PsyDAG**, Monday, June 21, 2010 at 12:27pmAre you looking for the average or the individual score? This would be for the latter. For the former, you need to have the sample size to find the SE (see following post).

Z = (score - mean)/SD

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to that Z score.
