IQ reference chart

IQ reference chart

IQ reference charts are tables, suggested by psychologists to divide intelligence ranges into various categories [Wechsler, D. (1944). "The Measurement of Adult Intelligence". Baltimore: The Williams & Wilkins Company.] [Reber, A.S. (1995). "The Penguin Dictionary of Psychology", 2nd ed. Toronto: Penguin Books.] . As reference charts, they are not to be taken as absolute or very precise. The reason for this is the lack of a uniform definition of intelligence and the current inability to wholly quantify it in a scientific manner. To get a "true" IQ score, multiple IQ tests must be taken since professionally administered IQ tests are only roughly 96% accurate. [ [http://www.cps.nova.edu/~cpphelp/WAIS-R.html Wechsler Adult Intelligence Scale-Revised ] ] The average of multiple tests, usually at least three, is considered that person's "true" IQ score. However, these tests must be taken within a relatively short period of time, normally under one year for three or more tests.
