a number intended to indicate a person's level of intelligence: It is the mental age (as shown by intelligence tests) multiplied by 100 and divided by the chronological age.
1. originally, the ratio of mental age to chronological age; that is, MA/CA 3 100. 2. today, the score on an intelligence test, calculated by comparing a person's performance to norms for her or his age group. (349)
A ratio measure to indicate whether a child's mental age (MA) is ahead or behind his chronological age (CA); specifically IQ = 100 x MA/CA. See also deviation IQ, mental age.
The number computed by dividing a child's estimated mental age by the child's chronological age, and then multiplying this number by 100. go to glossary index
A standardized measure indicating how far an individual's raw score on an intelligence test is from the average raw score of his or her chronological age group.
The measure of an individual's cognitive abilities, as measured by an intelligence test.
The ratio between a person's chronological age (measured in years) and mental age (as measured by an intelligence test), multiplied by 100.
A measure of someone's intelligence as indicated by an intelligence test, where an average score is 100. An IQ score is the ratio of a person's mental age to his chronological age multiplied by 100.
a measure of a person's intelligence as indicated by an intelligence test; the ratio of a person's mental age to their chronological age (multiplied by 100)
A quantitative representation of cognitive ability which results from testing a sample of cognitive skills. The formula is intellectual age divided by chronological age, multiplied by 100. For example, someone 10 years old with an intellectual age of 13 would have an IQ of 130.
currently IQ is calculated by estimating where, under the normal distribution curve, someone's performance on an IQ test places him or her. The curve is standardized such that the mean score is 100 and the standard deviation around the mean is 15. An average IQ is therefore between 85 and 115. The scale will go from 55 to 145 (three standard deviations below and above the mean).
A measurement of thinking (cognitive) ability that compares an individual with others in his age group.
A scale unit used in reporting test scores that attempt to measure "general intelligence." It represents a ratio between tested mental age to chronological age.
A measure of an individual's intelligence potential based on a set of norms derived from standardized tests.
a measurement of cognitive ability comparing a student with other students of the same age
A test that calculates a person's purported mental capacity. IQ tests have become increasingly controversial because critics claim they measure only a narrow band of intellectual strengths. Other critics claim the tests are biased against members of some minority groups.
It is a measure of general intelligence obtained by testing. It consists of either a ratio of mental age to chronological age or a score of deviation from an expected test performance by age. [Click Here To Return To List
Numerical score received on an intelligence test.
A scale unit used in reporting intelligence test scores, based on the ratio between mental age and chronological age. The decimal point is omitted so that the average IQ for children of any one chronological age is set at 100. See also chronological age, deviation IQ, mental age.
An intelligence quotient or IQ is a score derived from a set of standardized tests of intelligence. Intelligence tests come in many forms, and some tests use a single type of item or question. Most tests yield both an overall score and individual subtest scores.
