Quizplus · Accepted Answer

An intelligence quotient (IQ) is a measure of intelligence originally computed by dividing a person's mental age (as determined by an intelligence test) by his or her chronological age and multiplying the result by 100. This method was developed by French psychologist Alfred Binet in the early 20th century and is still used today in modified forms for some intelligence tests.
