Question

Quizplus · Accepted Answer

IQ scores are determined by comparing an individual's performance on intelligence tests to the performance of others in their age group. The scores are standardized based on age, so an individual's score reflects their relative standing within their age group. Therefore, even if an individual gains more knowledge or skills as they get older, their relative standing among their peers may not change, resulting in a stable IQ score.
