<p>there are 3 standard deviation in IQ : 15 16 24.
i dont know what’s the diffrent but i think it’s the length of the straight line between the IQ bell curve
example 130 in sd 15 but it’s 132 in 16 and 148 in 24</p>
<p>top IQ 130+ is top 2%</p>
<p>i’m wondering about IQ of harvard student, it’s curiousity :D</p>
<p>140+ in sd 15 is kind of genius </p>
<p>are all harvard student genius ?</p>
