Detailed explanation-1: -IQ was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100. Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/10 × 100, or 120.
Detailed explanation-2: -The formula for the calculation of the Intelligence Quotient (IQ) is MA/CA x 100. The shorthand for intelligence quotient is IQ. The intelligence quotient (IQ) is a numerical indicator of a person’s intelligence.
Detailed explanation-3: -An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ). Thus, a subject whose mental and chronological ages are identical has an IQ of 100, or average intelligence.
Detailed explanation-4: -So, if an individual of 10 years of age had a mental age of 10, their IQ would be 100. However, if their mental age was greater than their chronological age (e.g., 12 rather than 10), their IQ would be 120. Similarly, if their mental age was lower than their chronological age, their IQ would be lower than 100.
