Dr. Joel Schneider has (again) posted an amazing and elegant video tutorial to help individuals who engage in intelligence test interpretation understand whether composite/cluster scores should be interpreted as valid when the individual subtests comprising the composite are significantly different or discrepant (according to Dr. Schneider--"short answer: not very often"). It is simply AWESOME...and makes me envious that I don't have the time or skills to develop similar media content.
His prior and related video can be found here.
Clearly the message is that the interpretation of test scores is not simple and is clearly a mixture of art and science. As Tim Keith once said in a journal article title (1997)...."Intelligence is important, intelligence is complex." This should be modified to read "intelligence is important, intelligence is complex, and intelligence test interpretation is also complex."
