The categories of IQ vary between IQ test publishers as the category labels for IQ score ranges are specific to each brand of test. The test publishers do not have a uniform practice of labeling IQ score ranges, nor do they have a consistent practice of dividing up IQ score ranges into categories of the same size or with the same boundary ...
The relationship between IQ and academic performance has been shown to extend to one's children. In a study [12] measuring a range of family background characteristics they found that maternal IQ was a stronger predictor of children's test scores than any other family characteristics, including socioeconomic status. Maternal IQ predicted around ...
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.
The g factor [a] is a construct developed in psychometric investigations of cognitive abilities and human intelligence.It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks.
The IQ gains in the experimental group compared to the control group was 4.4 points. These gains persisted until at least age 21. [36] Citing a high correlation between rising literacy rates and gains in IQ, David Marks has argued that the Flynn effect is caused by changes in literacy rates. [37]
A number of studies have shown a correlation between IQ and myopia. [6] Some suggest that the reason for the correlation is environmental: either people with a higher IQ are more likely to damage their eyesight with prolonged reading, or people who read more are more likely to attain a higher IQ; others contend that a genetic link exists.

Various high-IQ societies also accept this test for admission into their ranks; for example, the Triple Nine Society accepts a minimum qualifying score of 151 for Form L or M, 149 for Form L-M if taken in 1986 or earlier, 149 for SB-IV, and 146 for SB-V; in all cases the applicant must have been at least 16 years old at the date of the test.
IQ tests had lower negative correlations with certain socially undesirable outcomes such as that children with high IQ were less likely to engage in juvenile crime. One example being a study finding a correlation of −0.19 (−0.17 with social class controlled for) between IQ scores and number of juvenile offenses in a large Danish sample.
