| Description: IQ scores form what mathematicians call a normal distribution—the famous "bell curve" you may have heard about. The two sides of a normal distribution curve are mirror images of each other. Thus, 34% of children score between 85 and 100, and another 34% score between 100 and 115. Likewise, 13% score between 70 and 85 and another 13% between 115 and 130. A few other human characteristics, such as height, are normally distributed as well.
