CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -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-2: -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-3: -Historically, IQ was a score obtained by dividing a person’s mental age score, obtained by administering an intelligence test, by the person’s chronological age, both expressed in terms of years and months. The resulting fraction (quotient) was multiplied by 100 to obtain the IQ score.

Detailed explanation-4: -Mental Age is based on intellectual development. Chronological Age is the number of years a person has lived. When a person’s mental age is equal to his chronological age, he is said to have a normal/average IQ. If an individual’s IQ lies in the 90-109 range, it means his/her IQ is normal/average.

Detailed explanation-5: -IQ stands for intelligence quotient and, in short, it is a measure of a person’s reasoning ability. In other words, an IQ test is supposed to gauge how well someone can use information and logic to answer questions or make predictions.
