IQ Test
An Intelligence Quotient or IQ is a
score derived from one of several different standardized tests
attempting to measure intelligence. The term "IQ," a translation of
the German Intelligenz-Quotient, was coined by the German
psychologist William Stern in 1912 as a proposed method of scoring
early modern children's intelligence tests such as those developed
by Alfred Binet and Theodore Simon in the early 20th Century.
Although the term "IQ" is still in common use, the scoring of modern
IQ tests such as the Wechsler Adult Intelligence Scale is now based
on a projection of the subject's measured rank on the Gaussian bell
curve with a center value (average IQ) of 100, and a standard
deviation of 15 (different tests have various standard deviations;
the Stanford-Binet IQ test has a standard deviation of 16).
Today IQ testing is used not primarily for children, but for adults.
Today we attempt to write tests that will determine an adult's true
mental potential, unbiased by culture, and compare scores to the
scores of other adults who have taken the same test. So today we
compare an adult's objective results to the objective results of
other adults, and determine how intelligent each test taker is
compared to all other test takers, instead of comparing test takers
to an arbitrary age related standard. Free IQ Test .
