Generic I.Q. Chart

Maintained by Darryl Miyaguchi
Last updated: May 18, 1997

 

The following is a chart of I.Q. scores from 100 to 202, using 16 I.Q. points per standard deviation. I have mapped in Mega (6th norming), Titan (1st norming), and Ultra Test (July 1, 1996 results) raw scores. The sigma column shows the standard deviation of each I.Q. score; sigma = (IQ-100)/16. The percentile for each I.Q. score was calculated using the Microsoft Excel function NORMDIST. The rarity column shows how many people in the general population are expected to achieve this percentile or higher. For example, 1 out of 100 people are expected to achieve an I.Q. score of 137 or higher. I have rounded numbers where appropriate.
