IQ Test Information
An IQ test seeks to measure an Intelligence Quotient (IQ) or a person's mental age. It is intended to provide an assessment of human intelligence.
Traditionally, IQ scores are place on a scale with 100 being considered average intelligence. Scores are adjusted so that one standard deviation is 15 points. By this definition, approximately two-thirds of the population would receive an IQ score in the range of 85 to 115.
There are many different tests that can be used to measure IQ. Some of the more common IQ tests include:
- Wechsler Adult Intelligence Scale (WAIS-IV)
- Stanford–Binet Intelligence Scales
- Das–Naglieri cognitive assessment system
- Woodcock–Johnson Tests of Cognitive Abilities
- Cattell Culture Fair III
- Raven's Progressive Matrices
- Differential Ability Scales
- Reynolds Intellectual Assessment Scales
Although all IQ tests are different, most of the tests attempt to measure areas such as:
- Verbal comprehension
- Perceptual Reasoning
- Mathematical reasoning
