IQ full form is Intelligence Quotient. It is a form of intelligence test that determines the numeral value of the relative intelligence of a person. An IQ test can measure mathematical ability, analytical reasoning, spatial recognition, and more. It was William Stern who created the acronym ‘IQ’ for the German term ‘Intelligenzquotient’ that he proposed in a book in 1912. The book was for a rating system for IQ tests (at the University of Breslau). 

One should note that IQs can easily change from situation to situation, depending on the circumstances. Additionally, age is a significant factor while determining IQ. Earlier, IQ was represented as a ratio of mental age to chronological age x 100. Presently, modern IQ determinants keep the average score as IQ100; the raw score is turned into a normal distribution with a mean of 100 and a standard deviation of 15.
