What is the average IQ for a 13 year old?

Answer 1

ideally, an average IQ should be 100 world wide. Your IQ is your mental age (the average age of someone who possesses your intellect) divided by your physical age (your actual age in years) multiplied by 100. Now if you are 13 and you have the intelligence of an average 13 year old, then the maths is 100(13/13)

Which is 13 (mental age) divided by 13 (physical age) multiplied by 100.

if your mental age and physical age are the same then your IQ will be 100 because a number divided by the exact same number is equal to 1 (except 0) and 1 x 100 is equal to 100. If your physical age is higher than your mental age then the number you will multiply by 100 will be less that 1. for example if a 13 year old had a mental age of 10 then their IQ would be 10/13 x100. Now a mental age is the average age associated with a score on an IQ test. If she had the score of an average 10 year old, her mental age would be 10. When i was 10 i was said to have an IQ of 160. This is because my test score was that of a 16 year old. 16/10 x 100 is 160. Age does not determine your IQ. Your intellect at a certain age compared to the intellect of others who are the same age determines it. our IQ can change. If you were to get a score when you were 10 then you were to get the same score when you were 11, your IQ would have been higher when you were 10. The more your mental age is larger than your physical age, the smarter you are. The smaller your mental age is than your physical age. The stupider you are. A baby can have a higher IQ than an adult. But the adult can still know 10000 times more than the baby. I hope this explains how the IQ system works.

Answer 2

The average IQ for ANY living person is 100.

IQ results form a bell curve. 95% of the population falls between 70 and 130 points, with 100 being the mid-point.

Answer 3

IQ tests are designed to always have an average of 100. So the average IQ for a 13 year old girl is 100.
