Units of IQ Rating. The IQ rating scale is built with a mathematical comparison of your mental age with your chronological age, and the result is multiplied by 100 for normalization. Lewis M.

IQ bell curve. Standardized IQ tests are designed so that the exact average (mean) IQ score in the general population is 100.

The Mensa qualifying IQ score is a score that puts you in the top 2% of the population in a bell curve like this one.
