Document Summary
You couldn"t compare a a (cid:883)(cid:882) year old to an 8 year old bc the (cid:883)(cid:882)has learned two. Intelligence quotient more years and the brain is more developed to allow for comparison of test scores among persons, l. terman devised the concept of intelligence quotient (iq) 100 is the average score, if higher than 100 you will get a superior children achieve an actual score intelligence. Population norms: iq is pretty well distributed throughout the population validity issues for iq tests. Iq tests scores are meant to predict ability to succeed in school (valid use) If you have high iq you tend to do better in school but it is a correlation not causal. But it is used bc they seem to be predictive of some portion of the variants of most behaviors that we produce. Minimal theoretical basis (no underlying construct was used to devise tests)
