CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Intelligence quotient (IQ) refers to mental age (MA) expressed as a ratio of chronological age (CA) multiplied by 100. For IQ to remain stable, MA must increase with CA over time. This is true until around 18 years, when intellectual abilities are usually fully developed.

Detailed explanation-2: -An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ). Thus, a subject whose mental and chronological ages are identical has an IQ of 100, or average intelligence.

Detailed explanation-3: -Mental age is based on your intellectual development, while chronological age is based on the calendar date on which you were born. If your chronological age and your mental age are the same, you are said to be of average intelligence.

Detailed explanation-4: -IQ, (from “intelligence quotient”), a number used to express the relative intelligence of a person. It is one of many intelligence tests. IQ was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100.

Detailed explanation-5: -Mental age is a concept related to intelligence. It looks at how a specific individual, at a specific age, performs intellectually, compared to average intellectual performance for that individual’s actual chronological age (i.e. time elapsed since birth).
