An intelligence quotient, or IQ, is a score derived from one of several standardized tests designed to assess human intelligence. The abbreviation "IQ" was coined by the psychologist William Stern for the German term Intelligenz-quotient, his term for a scoring method for intelligence tests he advocated in a 1912 book.[1] When current IQ tests are developed, the median raw score of the norming sample is defined as IQ 100 and scores each standard deviation (SD) up or down are defined as 15 IQ points greater or less,[2] although this was not always so historically. By this definition, approximately two-thirds of the population scores an IQ between 85 and 115, and about 5 percent of the population scores above 125.
