Question

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. what percentage of people have an IQ between 130 and 100?

Answer 1

Nearly 70 percent of the population has an IQ between 85 and 115 on most tests. The scores above 115 are generally considered as “high IQ,” and those above 130 to 132 (depending on the test taken) are usually considered highly gifted and are in the top 2 percent of the population.
