IQ stands for Intelligence Quotient. It is a score derived from a set of standardized tests or subtests designed to assess human intelligence. The IQ score is calculated 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) is multiplied by 100 to obtain the IQ score. For modern IQ tests, the raw score is transformed to a normal distribution with mean 100 and standard deviation 15. This results in approximately two-thirds of the population scoring between IQ 85 and IQ 115 and about 2 percent each above 130 and below 70.
It’s important to note that IQ scores are estimates of intelligence and have been shown to be associated with such factors as nutrition, parental socioeconomic status, morbidity and mortality, parental social status, and perinatal environment. However, a concrete measure of intelligence cannot be achieved given the abstract nature of the concept of “intelligence”.
