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.
On the majority of modern IQ tests, the average IQ Score is set at 100 with a standard deviation of 15 so that IQ scores follow a normal distribution of statistical data. This means that approximately 95% of the worldâs population have scores within two standard deviations (SD) of the mean (average IQ score).
