Intelligence Quotient, or IQ, is a measure used to assess human intelligence through standardized tests. These tests evaluate various cognitive abilities, including reasoning, problem-solving, and comprehension. The resulting score is intended to provide a numerical representation of an individual's intellectual capabilities compared to the general population. The average IQ score is set at 100, with most people scoring between 85 and 115. Scores below 70 may indicate intellectual disabilities, while scores above 130 suggest above-average intelligence. IQ tests have been widely used in educational and psychological assessments, but they are not the sole indicator of a person's potential or abilities.
