1 – What is IQ ?
It is the result of a psychometric test that provides a numerical indication of human intelligence.
Intelligence is the ability to react adaptively to new situations, think abstractly, understand complex ideas and solve problems. IQ is the abbreviation for “Intelligence Quotient”.
2 – What characteristics of intelligence does IQ measure ?
Performing an IQ test highlights several characteristics of an individual’s cognitive intelligence:
- Comprehension and verbal expression skills
- Categorical and conceptual reasoning
- Visual reasoning, spatial, location in space
- Logical, mathematical and geometric reasoning skills
- The speed of information processing.
3 – The representation of IQ on the Gauss curve
It is by taking the Gauss curv as a reference that we are able to calibrate our test on this website. The average is set at 100 taking into account the general population. The standard deviation is set at 15. We are talking about standard IQ.
68.2% of the population is within 1 standard deviation of the mean (100), and 95.6% of the population is within 2 standard deviations of the mean.
4 – Classification of IQ standard deviations in the general population
- 40 – 54 : Extremely Low
- 55 – 69: Very Low
- 70 – 84 : Low
- 85 – 99 : Low Average
- 100 : Average
- 101 – 115 : High Average
- 116 – 130 : High
- 131 – 145 : Very High
- 146 – 160 : Extremely High
