Average vs. Normal IQ: An Empirical Follow-Up.
Hess, Harrie F.; Worgull, Norman
The broad hypothesis that children whose histories imply the possible presence of an intellect-reducing condition will score lower on an IQ test than children whose histories do not imply such conditions was tested in a study designed to illustrate the distinction between average and normal IQ. Health and behavior histories of a sample of second grade children enrolled in the public schools of Clark County, Nevada, were obtained from their parents via a 35-item questionnaire. The Otis-Lennon Mental Abilities Test (OLMAT) was used as the measure of intelligence. Health Jeopardy (HJ), Behavior Jeopardy (BJ), and Total Jeopardy (TJ) scores were computed for each subject. These scores were then used to classify subjects into groups of increasing magnitude of jeopardy. Mean IQ scores for the groups and tests for significance of differences were computed. It was found that (1) there was no significant relationship between HJ indicators and IQ; (2) while almost all of the BJ indicators were related to OLMAT IQ in the predicted direction, some of the BJ indicators were and some were not significantly related to IQ; (3) TJ scores were found to be significantly related to IQ; and (4) the Low-Jeopardy Group, having less than two BJ indicators per subject, scored significantly higher on the OLMAT than the High Jeopardy Group. On the basis of the obtained differences, it was concluded that the distinction between normal and average IQ is not trivial. (Author/RH)
