deviation IQ

Deviation IQ is a way to measure a person’s intelligence by comparing their test score to the average score of people their age. It shows how far above or below the average they are, expressed as a number. For example, an IQ of 100 means you’re exactly average for your age group. Scores above 100 indicate above-average intelligence, while scores below 100 suggest below-average. This method helps ensure that IQ scores are consistent across different age groups, making it easier to understand and compare individual abilities within a population.
