Detailed explanation-1: -mental age, intelligence test score, expressed as the chronological age for which a given level of performance is average or typical. An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ).
Detailed explanation-2: -a numerical scale unit derived by dividing an individual’s results in an intelligence test by the average score for other people of the same age. Thus, a 4-year-old child who scored 150 on an IQ test would have a mental age of 6 (the age-appropriate average score is 100; therefore, MA = (150/100) × 4 = 6).
Detailed explanation-3: -Mental age is an estimate of a person’s cognitive development derived from raw score performance on intelligence, achievement, or neuropsychological tests. Mental age is most frequently estimated in children, likely due to the emergence and protracted developmental course of cognitive skills during this period.
Detailed explanation-4: -From Binet’s work, the phrase “intelligence quotient, ” or “IQ, ” entered the vocabulary. The IQ is the ratio of “mental age” to chronological age, with 100 being average. So, an 8 year old who passes the 10 year-old’s test would have an IQ of 10/8 x 100, or 125.
