B. accentuate the importance of reasoning over performance. C. [ have never been associated with the concept of mental age. D. provide an advantage to people who don't rely mainly on verbal skills: IQ classification is the
practice by IQ test publishers of labeling IQ score ranges with category names such as "superior" or "average."[1][2][3] There are several publishers of IQ tests. No two publishers use exactly the same classification labels. IQ classification labels have changed from time to time since the beginning of IQ testing a century ago. IQ scores have been derived by two different methods since the invention of IQ tests. The first method historically was the "quotient IQ," based on estimating a "mental age" of the test-taker (rounded to a specified number of years and months), which was then divided by the test-taker's "chronological age" (rounded to a specified number of years and months). For example, a mental age score of thirteen years and zero months for a test-taker with the chronological age ten years and zero months results in a quotient of 1.3 after doing the division. The division result was then multiplied by 100 so that scores could be reported without decimal points. Thus the score in the example would be reported as IQ 130. The current scoring method for all IQ tests is the "deviation IQ." In this method, an IQ score of 100 means that the test-taker's performance on the test is at the median level of performance in the sample of test-takers of about the same age used to norm the test. An IQ score of 115 means performance one standard deviation above the median, a score of 85 performance one standard deviation below the median, and so on.[4] Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number by either procedure. Deviation IQs are now used for standard scoring of all IQ tests in large part because they allow a consistent definition of IQ for both children and adults. ]
