It's important to note that IQ scores are not the only measure of a person's intelligence, and that cultural and educational factors can influence test results.

IQ stands for Intelligence Quotient, and it is a numerical score obtained from standardized tests that are designed to measure a person's cognitive abilities and potential. The tests aim to assess various aspects of intelligence, such as logical reasoning, spatial awareness, mathematical aptitude, language skills, and knowledge acquired through education.

An IQ score is calculated based on a comparison of the test taker's performance to the performance of others in their age group. The average IQ score is set at 100, and scores above 100 indicate higher than average intelligence, while scores below 100 indicate lower than average intelligence. However, it's important to note that IQ tests have limitations, and a person's IQ score does not fully define their intelligence, abilities, or potential.
