What is the normal IQ range?

Explanation:
IQ scores are designed with a mean of 100 and a standard deviation of 15, so most people fall within about one standard deviation of the mean—roughly 85 to 115. In this context, the range from 100 to 115 best represents scores around the center of the distribution and extending into the higher end while staying within normal functioning. It captures the typical performance you’d expect for what many would regard as normal. The other ranges either sit below the mean, push further into higher-than-average territory, or are too narrow to reflect the usual spread around the mean.
