Breakdown

As top 3% of the population, the calculation is 97.3657942589%. You can see the breakdown here in the .16 Standard Deviation (SD) column, which is snapshot above.

This means I am 1 in 38 people. So in a randomised room of 100 people representing the average human population there would be 2-3 people of my IQ in the room or higher.

Though humans generally pool in certain areas based on professions for IQ so there is not a normal population distribution in most environments.

Ie, if I go to the Opera there should be more than 2-3 people with an IQ as mine or above.
