What does the percentile attached to an IQ score represent?

• A. Relative rank within a normative sample
• B. Absolute intelligence level
• C. Predicts future grades
• D. Measures effort

Answer: (A)

Percentile attached to an IQ score shows how your performance compares to others in the standardization (normative) group. It indicates the percentage of people in the normative sample who score at or below your score. So, if you’re at the 75th percentile, you scored higher than about 75% of peers of the same age and lower than about 25%. This is a relative rank based on a large, age-specific reference group, not an absolute measure of intelligence. It doesn’t directly predict future grades or reflect how hard you worked.
