Hm. I think you mean, 'raw IQ numbers are meaningless without
reference to the error rate specific to the test in question.'
If the standard deviation differed based on what test was taken, it
wouldn't be "standard."

IQ tests do ultimately just tell you how well a person took a test -
however, good IQ tests (the current WAIS, the NART or NAART, etc) are
designed to approximate 'G', and this is usually accomplished through
painstaking validation procedures. All of the quality published IQ
tests out there are designed to approximate the same construct ("G" -
or "general intelligence"), so actually, a 110 IQ score on the National
Adult Reading Test (NART) *is* comparable to a 110 score on the
Wechsler - precisely because of the way both instruments were
designed.

Hope you'll excuse me. I do a lot of psychological assessment for a
living and I thought this was interesting enough to butt into.
