Question

How I.Q. is distributed in the population?

Answer 1

IQ (Intelligence Quotient) is typically distributed in the population in the shape of a normal curve, also called a bell-shaped curve. This pattern shows that:

• Most people have an average IQ, which falls between 85 and 115.
• The average IQ is set at 100.
• About 68% of people fall within the average range.
• Around 14% of people have above-average IQs (115-130), and about 2.5% are considered gifted (above 130).
• Similarly, about 14% score below average (70-85), and another 2.5% may have intellectual disabilities (below 70).

This distribution helps psychologists understand how intelligence varies across the population and provides a basis for comparing individual scores.
