The book includes the authors' calculation of average IQ scores for 60 countries, based on their analysis of published reports. It reports their observation that national IQ correlates with gross domestic product per capita at 0.82, and with the rate of economic growth from 1950 to 1990 at 0.64.
The report stated that IQ scores measure important skills as they correlate fairly well (0.5) with grades. This implied that the explained variance (given certain linear assumptions) is 25%. "Wherever it has been studied, children with high scores on tests of intelligence tend to learn more of what is taught in school than their lower-scoring ...
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.
Doing so confirms IQ gains over time. Some IQ tests - for example, tests used for military draftees in NATO countries in Europe - report raw scores, and those also confirm a trend of rising scores over time. The average rate of increase seems to be about three IQ points per decade in the United States, as scaled by the Wechsler tests.
It estimated IQs for all US presidents, and validated the headline of the hoax, which stated Bush's was the lowest of any president in the last 50 years, though it estimates his IQ considerably higher (by nearly two standard deviations) than the 91 suggested in the hoax report. It rated G.W. Bush second to last since 1900, with an estimated IQ ...
Youngest or middle siblings may beg to differ, but this study of 250,000 Norwegian 18- and 19-year-olds published in Science magazine revealed they had an average IQ 2.3 points higher than their ...

A Perceptual Reasoning Index (PRI) can be derived from the raw scores on the Matrix Reasoning and Block Design subtests. A Full Scale IQ-2 (FSIQ-2) can be derived from the raw scores on the Matrix Reasoning and Vocabulary subtests, while a Full Scale IQ-4 (FSIQ-4) can be derived from the raw scores on all 4 subtests. WASI-II Subtests grouped by ...
