It is now recognized that there are no significant sex differences in average IQ, [1] [2] though performance in certain cognitive tasks varies somewhat between sexes. [3] [4] While some test batteries show slightly greater intelligence in males, others show slightly greater intelligence in females.
In the current IQ scoring method, an IQ score of 100 means that the test-taker's performance on the test is of average performance in the sample of test-takers of about the same age as was used to norm the test. An IQ score of 115 means performance one standard deviation above the mean, while a score of 85 means performance one standard ...
An intelligence quotient (IQ) is a total score derived from a set of standardized tests or subtests designed to assess human intelligence. [1] Originally, IQ was a score obtained by dividing a person's mental age score, obtained by administering an intelligence test, by the person's chronological age, both expressed in terms of years and months.
A recent study out of the University of Vienna shows that those scores, which are calculated via test responses, have been. One's intelligence quotient, or IQ, is regarded by many as being a ...
Leading up to the 1990s, IQ scores were consistently going up, but in recent years, that trend seems to have flipped. ... In a 1984 study, James Flynn noticed that intelligence test scores had ...
The current version of the test, the WAIS-IV, which was released in 2008, is composed of 10 core subtests and five supplemental subtests, with the 10 core subtests yielding scaled scores that sum to derive the Full Scale IQ. With the WAIS-IV, the verbal/performance IQ scores from previous versions were removed and replaced by the index scores.
A 2008 analysis of test scores across 41 countries published in Science concluded that "data shows a higher variance in boys' than girls' results on mathematics and reading tests in most OECD countries", the results implying that "gender differences in the variance of test scores are an international phenomenon". However, it also found that ...
