Correlation between Iq and SAT scores....

<p>Is there any?</p>

<p>The only strong correlation I could imagine is that there is no correlation. Not only do I think that IQ tests are unfair and biased (I mean, how can you expect to compare intelligence between a Harvard educated person and someone who has not ever read a book in inland China) but in my humble opinion they also have limited value when it comes to evaluating a person. What do they really say about a person? I have a friend who always scores mad high scores, but he is socially incompetent and unable to get through any type of interview with a prospective employer. A girl-friend of mine is the opposite - scores low but is an extremely successful saleswoman. </p>

<p>Now that I think about it, there might be a correlation between the traditional western-style IQ test and SAT's. But my point is that in the end, neither matter all that much when it comes to life, the universe, and everything. (Who did I just quote? 10 points...)</p>

<p>Well, 42 isn't much of an IQ or SAT score ;)</p>

<p>I agree completely except with the added fact that I know about the history of the SAT and know that the correlation between it and IQ tests was that it was born out if it,SAT=Glorified IQ test. However it does have some value if as a range of 200-250 above a 1000 and 100-150 (only reason range changes is due to the weird scoring system that make 1 raw point in 700 range a bigger a bigger scaled loss than in 500 range, obviously to limit 1600's, what other test are equal questions not given equal weight)</p>

<p>I did these calculations using a method similar to that for my GRE to IQ Estimator. The lowest point of reference was the theoretical average IQ of high school students being 110 and the current average SAT I V+M (verbal + math) score being 1019. Everything below that is extrapolation. Also note that the decimal places give the impression that the numbers are more precise than they really are. </p>

<p>This means my 144 iq will only get me a 1490 sat score. :(</p>

<p>Oh, i guess I should mention, I dislike iq tests as well. Iq tests only measure one facet of one's intelligence, true intelligence can never be measured, at least not through iq tests.</p>

<p>IQ scores are not a predictor of SAT scores. Neither is parental income. There is variance in SAT scores at any particular level of IQ, and variance in SAT scores at any particular level of parental income. I know of at least two scholarship programs that are granted to young people who have BOTH low family income and high SAT scores. A child who can rise above his circumstances is the kind of child most likely to get that kind of scholarship.</p>

<p>As 2bad says, the SAT was born out of the IQ test, back in its early days. Over the years, ETS has tried to disassociate the two, mainly because of negative public feelings about the IQ test as elitist and deterministic. Originally the "A" in SAT stood for "aptitude," a word associated with IQ tests; then it was changed to "achievement" to suggest that it measures something more than the chimerical "GI(general intellegence)" that IQ-type tests purport to measure; however, that too was dropped, as too controversial, since it's not all that clear that the SAT measures scholastic achievement. Now it stands for nothing, just the SATs, not an acronym.
Some argue that the current SAT moves further away from IQ testing than ever before, with heavier emphasis on things taught in schools.</p>

<p>Or maybe things taught in schools have heavier emphasis on the SAT test. . . . hmm</p>

<p>I love reading about the history of the SAT, im sure if more people knew the history of the SAT they would put less stock in it.</p>

<p>people should do the same for iq tests. Seriously, it is totally polarizing our society. I mean I've read about people too smart for their own good, and they don't live good lives. :(</p>

<p>I think IQ tests have been discredited alot already(hence why ETS never associates SAT with IQ tests), You hear about kids and adults with extremely high IQ tests scores who dont achieve a thing while people with lower IQ scores that win Nobel Prizes become CEO's ,cure cancer...</p>

<p>Of course there is. But that just means that the IQ score and parental income are not the sole determinative factors (finance is not destiny). It doesn't mean that there is no correlation.</p>

<p>There is no point in debating correlation because they are basically the same thing born out of the same era and same principle.The only reason there is doubt is due to the effort of ETS which prefers SAT's not be affiliated with IQ tests.</p>

<p>hmmm, while that may be true, numbers should not be used to define people. It really does anger me when people with low numbers are considered stupid. In addtion, high numbers produce intellectual elitists. People have even resorted to calling the president stupid because supposedly he has a below average number.

<p>I have praised your statistical acumen in other threads, so I'm not going to disagree with you much here, but I invite you to look at the context in which I was replying in this thread. </p>

<p>I find this kind of research interesting, and I actually agree with the idea that there isn't a dime's worth of difference between a current SAT test and a current IQ test in sorting people into a rank order on a construct that I think is best deemed "scholastic aptitude," but the earlier poster made a big error that I thought you, of all people, would pick up. </p>

<p>Let's suppose it is shown that an IQ score of 130 on a particular brand of IQ test indicates a rank order at the 98th percentile of the general population (which is approximately correct for most current IQ tests). Does that mean that a person who scored 130 on an IQ test can be sure to score at the 98th percentile level on the SAT? Well, no. And the reason we can't be sure of that is that the two kinds of tests are not PERFECTLY correlated: the correlation coefficient between any one brand of IQ test and any other, and between any brand of IQ test and the SAT, is always less than the 1.0 that indicates perfect positive correlation. It may be that a person who scored 130 on an IQ test will ace the SAT. It may also be that a person who scored 130 on an IQ test will be at the median level on the SAT. It would be an interesting empirical question to look at just how broad the confidence intervals are for "new" SAT I scores at different IQ levels on the newest IQ tests--but no one knows today because all the tests are too new for there to be any good data on this issue. On the previous version of the SAT (the one used up till January of this year) and earlier versions of IQ tests, you wouldn't know FOR SURE what your highest possible SAT score was unless your IQ score was quite low--because quite a few people exceeded their IQ percentile rank when they tested on the SAT I, as would be expected when comparing any two tests that aren't perfectly correlated. </p>

<p>That's the error I was responding to. The item content of past SAT I tests is published and available in public libraries or high school libraries to most of the test-taking population. LOTS of people could get 1600s (um, 2400s) on the SAT I, if they would turn off the TV, put away the video games, read challenging books, practice challenging math problems, and practice writing SAT-style essays. They don't have to worry about what their IQ score was on some previous occasion, nor should they worry overly much about how much money their parents make. Maybe their parents are hidden geniuses whose intelligence was never appreciated in the job market. ;) I know middle-schoolers who have aced one or the other sections on the previous SAT, and they are not all from wealthy families, nor are they all kids who have "ceilinged" on an IQ test.</p>

<p>I'd be willing to bet a lot of money that there is a correlation between SAT scores and IQ scores. Especially after reading the article above confirming it. (Of course, they may be wrong.)</p>

<p>People get too wrapped up in anomaly when talking about correlation. Tokenadult, you fell right into this with your post. Someone always says something like this, "Well I know this one guy who got a 130 on their IQ test, but only got a 900 on the old SATs" or "There's no correlation between college and income. Bill Gates dropped out of Harvard and he's the richest man in America! You don't need college."</p>

<p>Correlation doesn't mean perfect correlation.</p>

<p>Predictor doesn't mean exact predictor.</p>
