| Description: In a large population, IQ scores tend to be distributed on a normal curve. On most tests, about 68 percent of people will score between 85 and 115; about 95 percent will score between 70 and 130; and about 99.7 percent will score between 55 and 145. In any actual sample, however, the distribution will depart somewhat from the theoretical ideal.
