How do you calculate IQ with mental age and chronological age?
The IQ score was calculated by dividing the test taker’s mental age by his or her chronological age and then multiplying this number by 100. For example, a child with a mental age of 12 and a chronological age of 10 would have an IQ of 120 (12/10 x 100).
What is the formula to calculate IQ?
The equation used to calculate a person’s IQ score is Mental Age / Chronological Age x 100. On most modern IQ tests, the average score will be 100 and the standard deviation of scores will be 15.
Why do we multiply the formula of IQ by 100?
A person’s IQ score was originally calculated by dividing a person’s mental age by their chronological age and then multiplying by 100. Or, MA ÷ CA × 100. So IQ is a measure of the mismatch between a child’s mental and chronological ages.
How do you calculate mental age from IQ?
Write down your score in the following formula: IQ=MA/CA * 100, where “MA” is your mental age and “CA” is your chronological age. For example, if your chronological age is 10 and your IQ score is 120, the formula would read, 120=x/10 * 100, where “x” is your mental age.
