IQ

IQ or Intelligence Quotient is a measure of a person's cognitive abilities in relation to their age group. It is a score derived from several standardized tests designed to assess human intelligence.

History

The term "IQ" was coined by the psychologist William Stern for the German term Intelligenzquotient. Stern's term was then popularized by psychologist Lewis Terman at Stanford University.

Calculation

IQ 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 is multiplied by 100 to obtain the IQ score.

IQ Tests

There are a variety of IQ tests which include the Stanford-Binet Intelligence Scales, the Wechsler Adult Intelligence Scale, and the Wechsler Intelligence Scale for Children.

Criticism

Critics argue that IQ tests do not fully encompass all forms of intelligence. For example, Emotional Intelligence and Social Intelligence are not measured in traditional IQ tests.
