Standarized tests like IQ or ACT/SAT don't prove jack shizzle. I sucked at all 3, yet somehow I graduated with a 3.92 in my mba and am a level3 cfa candidate.
The new SAT has a very low correlation with IQ tests, but the previous two versions had high correlations. There is a .5 correlation between IQ and grades, so don't think good grades automatically proves that you have a high IQ too.
A .5 correlation with something is a pretty high correlation. Now, if the correlation was .1, then I'd say it was "very low". Statistically speaking, saying something is correlated with another on a magnatude of .5, is pretty high.
Sure, good grades doesn't prove you have a high IQ. However, good grades in a graudate level education, competing with other graduate level students in a good school probably shows you are higher intelligence than most.
If we were talking high-school gpa, that'd be something else. If we were talking underwater basket weaving, again, something else.
A .5 correlation is moderately high, but definitely not "very high." The average IQ of someone with a Ph.D. is between 128 and 131, SD 15... in the world of high intelligence, that is below average. The average IQ obtained on high-range IQ tests (ones that measure up to and above 4 standard deviations) is about 142 to 144, SD 15.
Where did I say "very high? I know people love putting words in other's mouths, but you are going a bit far. Do you have evidence of your Ph.D. numbers? I'd love to see proof of that, not to mention your sd numbers. I'd never really equate a PhD in most fields to somebody that was super smart, PhD is a research degree, which does require a high intellect, but not at the very top end. Furthermore, IQ tests a wider range of topics, requiring a more well-rounded individual, not just field specific, so i wouldn't be too surprised at a difference.
How are you coming up with your "SD" numbers? What is your sample size, how is your sample generated? Is it skewed? Why are you assuming that IQ = intelligence, do you have a null hypothesis that it doesn't? What are your critical values? What are your p-values? Are you more likely to commit a type I or type II error in your hypothesis if you even considered the fact that IQ isn't directly correlated to actual intelligence? I have known many "intelligent" people that suck at life.
As the poster mentioned above, you may think you are pretty badass by coming on a forum and spouting "SD", but to me, it's just something to increase your e-penis. Util you can do GARCH tests in your head, or you know multi-variable statistical rules by heart, you aren't jack.
