Statistics

Mean results by country

The mean results are displayed by the Cattell distribution. Only countries with at least 100 taken tests are displayed.

Result distribution

The results of the test will be fitted to follow the perfect standard deviation according to the definition of the intelligence quotient. Thus the average value of the test is 100 and the portions of different results are precisely correct. In other words, exactly 50 per cent of the test results will be left on both sides of the average value.

The underlying chart demonstrates the shares of different results by both the Cattell distribution, which the test uses, and the Stanford distribution.

Level	This test (Cattell)	Stanford	Proportion in the population
Genius	over 171	over 144	0,13%
Highly intelligent (Mensa level)	148-171	132-144	2,15%
Clearly above average	124-147	116-131	13,59%
Somewhat above the average	100-124	100-114	34,13%
Somewhat below the average	76-99	84-99	34,13%
Clearly under the average	52-75	68-83	13,59%
Low	under 52	under 68	2,28%
