Intelligence quotient is the full form of IQ. IQ is the total score obtained from a series of standardized measurements or subtests designed to measure individual intelligence. Psychologist William Stern invented the abbreviation "IQ" for the German word Intelligenzquotient, a word he proposed in a book published in 1912 for the University of Breslau's IQ test scoring system.
IQ may vary from scenario to scenario. Many techniques test a person's IQ. The number derived from an IQ test represents an individual's relative intelligence. You can measure a person's IQ using one of the many standardized test designs for access to human information. An IQ standardization sample can be defined as an IQ of 100. The deviation up and down is fixed at 15 IQ points. According to one survey, two thirds of the population have scores between an IQ of 85 and an IQ of 115. Only 5 percent of people have a score of 125.
