The resulting fraction quotient was multiplied by to obtain the IQ score. Scores from intelligence tests are estimates of intelligence.

An IQ score of means performance one standard deviation above the mean, while a score of 85 means performance one standard deviation below the mean, and so on. By the current "deviation IQ" definition of IQ test standard scores, about two-thirds of all test-takers obtain scores from 85 to , and about 5 percent of the population scores above i. When IQ testing was first created, Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number regardless of testing procedure.
