What Is an IQ Test?
An IQ test is an assessment that measures a range of cognitive abilities and provides a score that is intended to serve as a measure of an individual's intellectual abilities and potential. IQ tests are among the most commonly administered psychological tests. In order to understand what these scores really mean, it is essential to look at exactly how these test scores are calculated. Today, many tests are standardized and scores are derived by comparing individual performance against the norms for the individual's age group.
Historically, IQ tests have been scored in one of two ways. In the first method, a person's mental age was divided by their chronological age and then multiplied by 100. The other methods involve comparing scores against the scores of others in the individual's same age group. Many different tests are in use today including the afore mentioned Stanford-Binet and the Wechsler Adult Intelligence Scale, as well as the Woodcock-Johnson Tests of Cognitive Abilities. Each individual test is different in terms of exactly what is being measured, how it is scored, and how these scores are interpreted.
