Before people state strong assumptions one way or the other, have there ever been any studies that measured the relationship between test scores and IQ? If so, what did they say?
It’s an IQ test. Not a culture fair one, like Raven’s Progressive Matrices, but it’s as much an IQ test as coarse, quick and dirty one like Wonderlic is.
> Scholastic assessment or g? The relationship between the scholastic assessment test and general cognitive ability
> There is little evidence showing the relationship between the Scholastic Assessment Test (SAT) and g (general intelligence). This research established the relationship between SAT and g, as well as the appropriateness of the SAT as a measure of g, and examined the SAT as a premorbid measure of intelligence. In Study 1, we used the National Longitudinal Survey of Youth 1979. Measures of g were extracted from the Armed Services Vocational Aptitude Battery and correlated with SAT scores of 917 participants. The resulting correlation was .82 (.86 corrected for nonlinearity). Study 2 investigated the correlation between revised and recentered SAT scores and scores on the Raven's Advanced Progressive Matrices among 104 undergraduates. The resulting correlation was .483 (.72 corrected for restricted range). These studies indicate that the SAT is mainly a test of g. We provide equations for converting SAT scores to estimated IQs; such conversion could be useful for estimating premorbid IQ or conducting individual difference research with college students.
Yes. If you look you will find published literature on the subject. The plots plotting SAT/ACT and IQ will have an obvious trend but be very noisy. Hence why they are poor IQ tests, you can have a decent guess at someone's IQ based on their test results but it's not ideal.
