Solution and Explanation
Step 1: Define IQ.
IQ (Intelligence Quotient) is a measure of a person's intellectual abilities in relation to others. It is calculated by dividing the individual's mental age by their chronological age and multiplying by 100.
Step 2: IQ Formula.
The formula for calculating IQ is: \[ IQ = \frac{\text{Mental Age}}{\text{Chronological Age}} \times 100 \]
Step 3: Explanation.
Mental age refers to the age at which an individual performs intellectually, while chronological age refers to their actual age. The formula helps determine how an individual's intelligence compares to the average person of the same age.
