INTELLIGENCE QUOTIENT(IQ)

The Intelligence Quotient (IQ)

IQ is an acronym for Intelligence Quotient. So what is IQ? The IQ is a measurement of your intelligence and is expressed in a number.

A person's IQ can be calculated by having the person take an intelligence test. The average IQ is 100. If you achieve a score higher than 100, you are smarter than the average person, and a lower score means you are (somewhat) less smart.

An IQ tells you what your score is on a particular intelligence test, often compared to your age-group. The test has a mean score of 100 points and a standard deviation of 15 points. What does this standard deviation mean? It means that 68 percent of the population score an IQ within the interval 85-115. And that 95 percent of the population scores within the interval 70-130.

Some examples

What does it mean when your IQ is 100? That means that half of the population scores higher than you. The other half scores lower than you. And what does it mean when you have an IQ of 130? That means that 97,5 percent of your age group scores lower than you.
