An intelligence quotient (IQ) is a total score derived from several standardized tests designed to assess human intelligence.
The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligenzquotient, his term for a scoring method for intelligence tests at University of Breslau he advocated in a 1912 book.
Historically, IQ is 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 is multiplied by 100 to obtain the IQ score.
Having said that, let's now explore the IQ world and see what facts makes this unique ubiquitous ability fascinating to man.
