A chart for the better evaluation of intelligence quotients

Abstract

"The intelligence quotient of a subject may be obtained by dividing his mental age by the average mental age of subjects of his chronological age." The computation of the intelligence quotient is considered, with its relation to the growth curve of intelligence. A chart is presented "for the convenient calculation of intelligence quotients with Otis' mental ages as the divisors." (PsycInfo Database Record (c) 2025 APA, all rights reserved)
