Just curious as to how they are calcualted?
Example: My daughter got a Tscore of 82 on the RIAS "Verbal
Reasoning" subtest.

Is there a way to calculate how many problems she got right or wrong from the Tscore?
here http://jpa.sagepub.com/cgi/reprint/25/4/402.pdf it says that there are a total of 48 items on that subtest.

Would a "perfect" score = 100 tscore?
