I've been asked by a couple of individuals who have read the psych report to explain why the IQ scores from two different instruments were different (60 vs 77). The tests in question provide a perfect opportunity (a "teachable moment") re: IQ score differences due to different abilities being measured by different instruments....and will allow me to demonstrate a new feature that I plan to further develop. Stay tunned. I am at a conference and the follow-up explanation of a possible reason (the reasons can be multiple) for the difference may not surface here for a few days...or not until I return home.
As a tease, the new feature will be a visual-graphic comparison of the differential CHC ability coverage by different IQ tests, via what I am calling the "IQ Test CHC DNA Fingerprints" of different intelligence batteries.
