IQ (Intelligence Quotient) is a standardized score from tests measuring cognitive abilities like reasoning, problem-solving, and memory, comparing an individual's mental performance to their age group, with the average set at 100. It's a numerical representation of intellectual capability, derived from various subtests, that helps identify learning needs and guide educational or career paths, though it doesn't capture the full scope of human intelligence.
