**PsyDAG**, Thursday, May 1, 2008 at 1:03pmZ score = (x-μ)/SD, where x is the individual score, μ = mean, and SD = standard deviation.

Once the Z score is obtained, look it up in a table in the back of your statistics text called something like "areas under the normal distribution" to get the probability.

I hope this helps. Thanks for asking.
