IQ = (Mental Age/Chronological Age)X100

..rather than age.

Be wary when you go to “find out your IQ” however. Online tests aren’t reliable. I remember when I was 11 or 12, all of the kids in my class when to tickle.com for their IQ results, and it was ridiculous. There are so many factors that set off a red flag when you go to get your results from an online IQ test.

For example, you can go take a personality test online and it will be far from the truth… So you’ll dismiss it. But you go take an IQ test online and it’s a high score, so you assume it must be true.

See the problem there? There’s nothing that makes these IQ tests better than those personality tests.

If you’re truly curious as to what your IQ is, go to a psychologist who can give you proper testing.

IQ = (Mental Age/Chronological Age)X100

If mental capability is more than the average intelligence of many children at that age group means having more IQ (that is IQ is more than 100).

Average IQ at any age is equal to 100.

That is a 11 year old is having the average intelligence of all his age group , then his IQ is 100.

This IQ is assessed by tests on verbal, spatial and numerical abilities.

According to the WISC/WAIS scoring manual scores that fall in the 90 to 109 range are considered “average”. The score of 100 falls on the 50th percentile.

Avg of 90-100

I.Q. is not determined by age.
