IQ stands for intelligence quotient. Supposedly, it is a score that tells one how 'bright' a person is compared to other people. The average IQ is by definition 100; scores above 100 indicate a higher than average IQ and scores below 100 indicate a lower that average IQ. Theoretically, scores can range any amount below or above 100, but in practice they do not meaningfully go much below 50 or above 150.

IQ of 113 falls in the category of high average. 16.1% of population falls in this category with IQ's of 110 to 119.

Half of the population has IQ's of between 90 and 110, while 25% have higher IQ's and 25% have lower IQ's. IQ of over 130 is considered very superior. Only 2.2% of population has this level of IQ. If you score this high in IQ tests, you may be able to qualify for Mensa, which is an organisation for highly intelligent people.
