    SO thats why you did it?

    So intelligence = pattern recognition?

    heh. check out the ad at the bottom of this page while i was browsing. how apt though i wonder what that iq test is like ...

    I had a true educational assessment done back in November. I've had them done at various times of my life since I was confirmed as a gifted learning disabled student. They can take many hours to complete and so much of the results are determined by how the one administering the test interprets your responses/actions.



    My full-scale IQ result is 125; however, this is deceiving in my case because my language based skills actually score around 110 while my non-verbal reasoning skills score 140+. So like I said, my full-scale score underemphasizes some of my skills and over emphasizes others, and therefore really isn't very useful.



    If you ever get the chance to have the assessment, I recommend it, especially if you live in a place or goto a school that will pay for it.



    Cheers,



    PS. 100 is average. The scale has something to do with relationships, 110 being the 75th percentile, 125 being the 90th.. etc etc. Somebody who knows more could explain it properly.

    That is what modern our modern interpretation of intelligence has become.

    Not quite:



    The distribution is some specific form of the gaussian curve ( I am not sure the exactly equation, but a list from this site is as follows).



    Code:


    IQ Percentile

    65 01

    70 02

    75 05

    80 09

    85 16

    90 25

    95 37

    100 50

    105 63

    110 75

    115 84

    120 91

    125 95

    130 98

    135 99







    If I was keen, I would plot these parameters and get the particular constant of the gaussian, but I don't care.

    I think you mean "If my IQ were high enough, I would plot these in my head and put them in a row with fake versions, not tell you what they were, and ask you to find a pattern."

    the higher the score the more you think like the person that made the test.

    IQ is on a normal (gaussian) curve, with a mean of 100 and a standard deviation of 15 or sometimes 16. That means that if you have a score of 130, you're two standard deviations above the mean, or in the top 2% of the population - that's a characteristic of all normal curves. That's why I always enjoy looking at people's scores on these internet discussions - 90% of people are in the top 5% of the population.

    Maybe you know this, why is the standard deviation 15%?



    Has any one actually done a broad cross population analysis other than looking for the average?



    The standard deviation could be 20% or 5%, why 15%?

    It's 15 for the same reason the mean is 100: It's just set that way in order to communicate results easily. You could transform the numbers into something else and it wouldn't make any difference. The (old) SATs and GREs have means of 500 and standard deviations of 100 per section. Some IQ tests are set to have a standard deviation of 16. It's just playing with numbers and doesn't have any empirical basis. (It's actually not 15%, it's 15 points.)



    Same with the mean - the 100 is completely artificial. In fact, IQ scores have gone up significantly over the past several decades (it's called the Flynn effect). But it's constantly re-centered so the mean stays 100 regardless. It's like we just can't get any smarter.

    Um, it makes no sense that they set a standard deviation. Given a large sample of test takers, a standard deviation will arise, but you cannot set that deviation a priori. If you try to do so, you artificially force a population to distribute itself about the mean in artificial ways...

    Well that's what they do. It's not empirical, it's just data transformation. If you get a standard deviation of 30, you divide by 2 and then add 50 to make the mean 100 again, et voila. You could set the standard deviation to 25 if you wanted, or pi, or whatever. Some tests set it to 16. It's merely convention, so everyone knows what a score means in percentile terms.

    So the concept of IQ as a multiplicative relationship to average at a certain age has been abandoned for this percentile?

    Yes definitely. It's not a mental age/chronological age "quotient" any longer.

    Our own little bell curve is starting to look like an inverse bell curve.

    Yeah, I always look for threads like this because they always amuse me. I don't know if the tests are biased, or people are just lying, or only people who do well report their results, or what. But the scores are always absurdly high.

    Given the shape of our curve... the average IQ on the boards is 160...



    heheheh...

    Okay, so only a little better than "normal" at 110. But I also had about 20 minutes to go. I get bored taking these tests. I either see it or I don't and I don't have much patience for working it out.
