The info I have
Mean 505
Std Dev 78.42
I do not know how to post a normal curve up here BUT if the data is a NORMAL curve then the percentile should look SOMETHING like this:
PERCENTILE SCORE
2.5 percentile 349
16th percentile 427
50th percentile 505
84th percentile 583
97th percentile 661
99th percentile 739
I hope this is right. Everyone will have to fill in the gaps b/c I do not know how! Actually I may not know how to do this at all! Your paper form in the mail will show your CORRECT percentile
Good luck
