The Statistics Behind This Number
This page uses the standard normal distribution model (mean 100, standard deviation 15) applied to a general population, the same convention used across most published cognitive assessments. It is a statistical model of population-level distribution, not a measurement of any specific individual or group. Your own result from our free IQ test is calculated the same way; see the full methodology for the formula.
