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.
IQ is a comparison of your test results to the results of people your own age. The average IQ is 100. The higher the graph goes, the more people who have achieved that score. As you can see from the graph, there is a bell-shaped distribution.
