•You'll have to see your score report but with a mean of 215 and SD of 20 (this is what it was when I took step 1), a 239 is at 88.5%. They don't report this on the score report anymore though, so you'll have to calculate the z score. It's been a long time since I've had statistics and I had to look it up myself to figure out mine. You can go to <a href="http://psych.colorado.edu/~mcclella/java/normal/normz.html" target="_blank">Z-Score</a>
to calculate this yourself and enter whatever the SD and mean were along with your score (Y) and selective cumulative as the graph and it'll calculate your percentile. It's very good, great job.•••••Hey Thanks, Jim. That is a nice link. I knew it was "roughly one SD over the mean" but given my statistics-challenged brain it's really nice to see it in graphical format and to estimate a rough percentile.
Maybe i'm obsessing, but after working so hard to study for the test it is nice to understand your result - especially since I haven't got my actual score report!
Cheers!
