To the very knowledgeable posters here- I would greatly appreciate more detailed clarification on the subtests scores and how they relate to the VIQ, PIQ, and FSIQ scores.

I see many posters who mention actual subtest scores, and lots of discussion on getting 19's, 18's and 17's. Please explain to me how those "scaled" scores turn into the numbers 130-160. Somehow I must have missed this in the past posts. If someone knows specifically for WPPSI, that would be even better.
Thanks in advance for your help.
