Final answer:
Five-year-old Jackson has an IQ of 120 which corresponds to a mental age of 6 years old, according to the Stanford-Binet IQ test.
Explanation:
The Stanford-Binet test measures intelligence and mental age. In this IQ test, a ratio of mental age to chronological age is calculated and then multiplied by 100 to get the IQ score. Therefore, having an IQ score indicates that the child's mental age is proportionate to his IQ in relation to a standard average.
Using the formula for the original Stanford-Binet IQ test, IQ = (Mental Age/Chronological Age) x 100, we can calculate Jackson's mental age. Given that Jackson's IQ is 120, and his chronological age is 5 years old, we can rearrange our formula to find his mental age: Mental Age = (IQ x Chronological Age) / 100. Plugging in Jackson's IQ and age, we find Mental Age = (120 x 5) / 100, therefore, Jackson's mental age is calculated to be 6 years old.
