Frequently asked questions about the IQ tests.
What is an IQ test?
Although subject to a margin of error, an individual's IQ can be calculated by taking an intelligence test. The average IQ score is defined as 100, with scores above or below indicating performance above or below average. Achieving a score higher than 100 indicates superior performance, while a lower score suggests below-average performance.

What IQ test types are there?
In a classic IQ test you will generally find questions related to numerical reasoning, logical reasoning, verbal intelligence and spatial intelligence. An IQ test that primarily measures abstract reasoning, either inductive or deductive, will often be a non-verbal IQ test. The latter is then called culture-fair because of that.
Both classic and non-verbal IQ tests make for valid and reliable IQ score measurements, although their definitions of intelligence do vary. Generally an IQ test consisting of more questions will have a higher reliability than shorter tests.
