Question

Quizplus · Accepted Answer

Binet used the ratio IQ, which is calculated as mental age divided by chronological age, multiplied by 100. This method compares a child's level of intelligence with that of other children in the same age group. The other options (deviation IQ, normal IQ, and valid IQ) refer to different types of IQ tests or methods of scoring, and do not specifically describe the mathematical approach used by Binet.
