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.
Average IQ is 100 with standard deviation of 15. The fourth standard deviation of the mean of IQ is about 160. which is extremely rare; only 3 out of 100,00 people ar at this level. An IQ of 175 is found in only 3 out of 10 million people.
