q2 i? Testing of 1000 non-selected children with the Stanford Revision supported the IQ as a valid expression of intelligence, found practically no sex differences, and found social-status differences not a disturbing influence in estimating mental age. → Kohs 1917

Entry 390 summarizes Terman, Lyman, Ordahl, Galbreath and Talbert's 1916 Journal of Educational Psychology article reporting the Stanford Revision applied to "1000 non-selected children," with the intelligence quotient "found a valid expression of intelligence" and practically no sex differences reported.

"Discuss tests upon 1000 non-selected children. Explain the basis and development of the revision. The intelligence quotient found a valid expression of intelligence. Practically no sex differences. Differences in social status not a disturbing influence in estimating mental age."

Discussion¶

Learner Variables¶

• Gender — predictor: outcomes differ by group: a gap reflecting circumstances and treatment, not a cause
