Quizplus · Accepted Answer

The original numerical formula of an intelligence quotient is mental age divided by chronological age multiplied by 100, as developed by Alfred Binet and Theodore Simon in the early 20th century. This formula compares the individual's performance on intelligence tests to that of their peers, taking into account their chronological age. The resulting number is the individual's IQ score.
