  You mean the median? :3

    But in a perfect bell curve, isn’t the median always the same as the average?

    And even if it’s not a perfectly symetrical bell curve, aren’t they generally close enough to ignore the differance

      Yes Yes, with IQ both are the ~same. It was more of a teasing joke.

  It can’t be that many.

    It’s not. I assure you there are far more outliers on the low end.

      I endeavour to be as stupid as possible so more people can be above average.

      But I’m sure there are more people with 200+ IQ than with <0.

        I understand that you’re saying there are more incredible geniuses than full on retards.

        However, IQ scores are a normal distribution with an arbitrarily defined mean of 100 and a standard deviation of 15.

        So, IQ scores of 0 or 200 are both 6.6 standard deviations from the mean. If IQ is truly a normal distribution, you’d expect the number of people with IQ scores <= 0 and the number with scores >= 200, to be exactly the same, simply because this is how the scores are defined.

        If you try to look up what proportion of the population falls outside 6.6 standard deviations, the z-tables don’t go out this far. It’s essentially 0%

  If we’re talking about IQ, than no. An IQ between 85 and 115 is considered average. This entails 68% of the population. So, only 32% of people are not average and only 16% are below average.

    The average is exactly one value and nobody has exactly that value. Since average~mean 50 % are below and 50 % above average.

    What you are talking about is a range that is around the average, specifically one standard deviation (=15 points) around the average/mean value, which is a completely arbitrary range and I do not know why you assign “average” to this range. 90 to 109 is a range I know to be attributed “average”, still arbitrary, but at least an actually established range.
