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: -IQ, or intelligence quotient A number representing a person’s reasoning ability. It’s determined by dividing a person’s score on a special test by his or her age, then multiplying by 100.
Detailed explanation-3: -At what age can you test a child’s IQ? While you can test a child’s IQ as early as 2 years and 6 months of age, the results may not be accurate and may in fact change with age. The best time to test IQ in children is between ages 5 and 8.
