Quizplus · Accepted Answer

Intelligence quotient (IQ) is calculated by dividing a child's mental age by his or her chronological age and multiplying the result by 100. Therefore, it reflects the relationship between a child's mental age and his or her actual age. Option A is not true because IQ is based on both mental age and chronological age. Option C is not true because the same mental age score does not have the same implication for children of different ages. Option D is not true because IQ is calculated based on the relationship between a child's mental age and his or her chronological age, not just on the number of items answered correctly.
