When the Stanford-Binet was first developed, the intelligence quotient was calculated by dividing the mental age (MA) of the individual by their chronological age (CA) and then multiplying the result by 100. This gave an IQ score that was a ratio of mental age to chronological age, expressed as a percentage. Therefore, the correct formula for calculating IQ is MA/CA x 100. Therefore, the best choice is D.
