Looking at the pattern of poll choices it appears the final choice should read ">=145" and you should select that option if your IQ is exactly 145.
I have an IQ of 148 by the WISC-III, I'm told that is the 99.98th percentile.
Example to count iq:
Tim here got 148 which are only achieved by 2 in 10000 according to this info (can be a bit different with different probability values)
You have to know the standard deviation and the middle. IQ scale has by definition 100 as middle. Tim got 148 which gives (148-100)/15 =3.2 and that is very good. There are a different scale with 24 in standard deviation which would bring tim 100+3.2*24 =176(.
This poll has
15 as standard deviation so it will be fault to put another s IQ in this poll
I do apologize for the typ-o in the poll, I shall try and fix it.
