Quizplus · Accepted Answer

Most current intelligence tests compare the test-taker's performance to the average performance of others their age. This allows for a more accurate assessment of the test-taker's relative intelligence compared to their peers. Comparing to one's own previous performance (A) would not provide a valid measure of intelligence, as it may be affected by practice or familiarity with the test. Comparing to the best possible performance of others of any age (C) would not be practical, as it is unlikely to have a representative sample of the entire population. Comparing to the best possible performance of others the same age as the test-taker (B) could potentially skew results if there is a particularly high-achieving age group in the population.
