What is an IQ score?

Your IQ score is based on the number of questions you answered correctly, the number of questions you answered incorrectly, and the difficulty level of the questions you completed. Your results are compared to the whole population to determine your IQ with a normal distribution with a mean of 100 and a standard deviation of 15. The average IQ score is 100. While approximately two-thirds of the population scores between 85 and 115, only 2.5% of the population scores above 130 and below 70.

This may sound very interesting and yet somewhat difficult. However, in simple terms, your IQ score reflects how well you can answer the questions in our test in comparison to everybody else around the world who has completed the same test. It is generally accepted that a high correlation exists between IQ scores and things like job performance and income.
