With standardized IQ tests, IQ tests are designed so that their scores have a âbell curveâ distribution in the general population with an average of 100. This curve has a peak in the middle where most people score and tapering ends where only a few people score. In statistics this is called a normal distribution.
The average IQ of the population as a whole is, by definition, 100. IQs range from 0 to above 200, and among children, to above 250. However, about 50% of the population have IQs between 89 and 111, and about 80% of the population have IQs ranging between 80 and 120, with 10% lying below 80, and 10% falling above 120.
