Detailed explanation-1: -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-2: -IQ which means intelligence quotient describes the intelligence level of an individual. It is calculated by dividing mental age (MA) by chronological age (CA) and then multiplying it by 100.
Detailed explanation-3: -The IQ of person is given by the formula, IQ=mc×100, where m is the mental age and c is the chromological age. If 80≤IQ≤140 for a group of 12-year children, find the range of their mental age.
Detailed explanation-4: -a numerical scale unit derived by dividing an individual’s results in an intelligence test by the average score for other people of the same age. Thus, a 4-year-old child who scored 150 on an IQ test would have a mental age of 6 (the age-appropriate average score is 100; therefore, MA = (150/100) × 4 = 6).
Detailed explanation-5: -The IQ score was calculated by dividing the test taker’s mental age by their chronological age, 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 = 120.
