Default Re: MENSA

What Does "IQ" Stand For, and What Does It Mean?
http://www.geocities.com/rnseitz/Definition_of_IQ.html
The average IQ of the population as a whole is, by definition, 100. IQs range from 0 to above 200, and among children, to above 250. However, about 50% of the population have IQs between 89 and 111, and about 80% of the population have IQs ranging between 80 and 120.

see http://www.mensa.org/
Membership in Mensa is open to persons who have attained a score within the upper two percent of the general population on an approved intelligence test that has been properly administered and supervised. There is no other qualification or disqualification for membership eligibility.

The term "IQ score" is widely used but poorly defined. There are a large number of tests with different scales. The result on one test of 132 can be the same as a score 148 on another test. Some intelligence tests don't use IQ scores at all. Mensa has set a percentile as cutoff to avoid this confusion. Candidates for membership in Mensa must achieve a score at or above the 98th percentile (a score that is greater than or equal to 98 percent of the general population taking the test) on a standard test of intelligence.

Here's the average IQ by state according to the Ravens APM:

Race differences in average IQ are largely genetic

Around the world, the average IQ for East Asians centers around 106; for Whites, about 100; and for Blacks about 85 in the U.S. and 70 in sub-Saharan Africa.
