**PsyDAG**, Wednesday, September 29, 2010 at 11:20amFind table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to that Z score. In this case, you are looking for the "area in the larger portion."

**PsyDAG**, Thursday, September 30, 2010 at 2:22pmMy "table thingy" has Z scores to two decimal places. If you have a 1.90 value, there should also be a 1.98 value. Use that.
