A numerical value that represents the results of a test that measures the degree of intelligence and development.


It is used as a rough standard for judging intelligence and for diagnosing and helping people with intellectual disabilities (mental retardation).


Intelligence is not simply knowledge or academic ability acquired through study, but rather the basic ability to deal rationally with various situations and environments, which is quantified in an easy-to-understand manner.


The test is done using a measurement called an intelligence test.

In the past, the main method of measuring intelligence quotient was to calculate it as 'mental age/living age x 100,' but now it is more often expressed as DIQ (Deviation Intelligence Quotient).
