What is the average IQ for a person who 15?

There isn't a definitive answer to this question, as IQ tests are not standardized for different age ranges. However, some research has suggested that the average IQ of a 15-year-old may be between 85 and 115, with a standard deviation of 15. This means that the majority of 15-year-olds would have IQ scores within this range, but some may have higher or lower scores. It is important to note that IQ tests are only one measure of intelligence, and there are many other factors that can contribute to an individual's intellectual ability.
