An IQ score represents your reasoning and thinking skills. It is computed by dividing your mental age by your chronological age and multiplying the result by 100. Your mental age is determined through a series of standardized tests.
For example, if your chronological age is 22 and an IQ test reveals that your mental age is 26, your IQ score will be roughly 118.
The scale that Alfred Binet and Theophile Simon, his collaborator, developed suggests that the average IQ score is between 85 and 115. A score of 100 is considered the average IQ for the whole population, according to a writer on the IQ Test Experts website. The IQ score of a genius is 140.
Other theories of intelligence clash with these concepts. For example, some theorists believe that factors such as emotional intelligence should play a role in determining an individual's competency.
