IQ is a comparison of your test results to the results of people your own age. The average IQ is 100. If you gave 1,000 people a really hard test, your results would look like this: The higher the graph goes, the more people who have achieved that score.
The IQ scale is open-ended. Your IQ is 100 times your mental age divided by your actual age. Mental age is the age at which your IQ test results would be average. So let's say you're 10 years old, but your IQ test results are those of an average 12 year old. Your IQ would be 100 x 12 / 10, or 120. If you are 10 years old and your IQ is 80, your IQ test results are average for an 8 year old.
