Intelligence quotient (IQ) is an age-related measure of intelligence and is defined as 100 times the mental age. The word ‘quotient’ means the result of dividing one quantity by another, and intelligence can be defined as mental ability or quickness of mind. An intelligence test (IQ test) is, by definition, any test that purports to measure intelligence. Generally such tests consist of a graded series of tasks, each of which has been standardized using a large, representative population of individuals. This procedure establishes the average IQ as 100. It is generally believed that a person’s IQ rating is hereditary and that the rate of development of a person’s mental age remains constant until about the age of 13 years, after which it slows up. Beyond the age of 18 little or no improvement is found.
