Question

Quizplus · Accepted Answer

IQ is calculated by comparing an individual's raw scores on IQ tests against population norms, which have been created through extensive testing and data collection. This allows for a standardized comparison between individuals and provides a measure of cognitive ability. Comparing an individual's performance on IQ tests over time (B) may provide information about changes in cognitive ability, but it does not calculate IQ. Comparing raw scores on one IQ test against another IQ test (C) or comparing performance on an IQ test with a test of multiple intelligence (D) are not methods for calculating IQ.
