The term IQ was first coined in 1912 by William Stern, term for a scoring method for intelligence quotient at the University of Breslau. Historically IQ score was measured by dividing a person’s mental age by a person’s chronological age multiplied by 100. So if an individual of age 10 years had a mental age of 10 their IQ would be 100.
Core for intelligence tests are estimates of Intelligence. for example distance and mass, nutrition, parental social economic, morbidity, parent, social status, and hereditary IQ.
