What percentage of people have an IQ between 85 and 115?
If we apply the empirical rule to IQ distribution, we can say that 68\% of people have an IQ between 85 and 115; 95\% – between 70 and 130; and 99.7\% – between 55 and 145. The percentile of a score is the percentage of people who score equal to or below the score.
What percentage of people in the world have an IQ of 145?

If we apply the empirical rule to IQ distribution, we can say that 68\% of people have an IQ between 85 and 115; 95\% – between 70 and 130; and 99.7\% – between 55 and 145.
What is the 2nd percentile of IQ?

IQ 125 is at the 95th percentile – 95\% of people have an IQ equal to or less than 125.
What does it mean to have an IQ of 125?

Knowing your IQ percentile lets you determine how you stack up against the rest of the population (read: whether you’ve got the brain it takes to become the second Einstein ).
