What is Intelligence Quotient Part 1

I.Q. (Intelligence Quotient) is an assessment of a person's ability to reason logically. It is a measure of intelligence that can be used to compare different people's ability to think or use your noodle (brain).

It is calculated by dividing the mental age by the chronological age. It is always displayed as a percentage however the percentage symbol is not generally displayed.

The mental age of a person is determined by a series of questions that measures factors such as spatial ability, mathematical ability, language ability and memory ability.

Generally IQ tests have questions from each of these four categories and are usually repeated with variation to ensure consistency of responses and reduce the ability to game IQ tests.

Researchers have found that for the most part, people who do well in one category will do similarly well in other categories. Based on this, they argue that there is an element of intellectual ability that affects the above factors.

Standardized IQ tests are usually conducted in controlled environments over a set period of time. Results can either be accompanied by a detailed analysis paper and/or explained by a trained professional or behavioral psychologist.

IQ tests are used frequently to diagnose or confirm developmental difficulties, by employers evaluating senior staff or by the health professionals.
