Hal was born on January 12, 1995 = 10 years (+ 9 months).
Hal would have to take the standard test determined by the Wechsler Intelligence Scale for Children. It contains two subscales: a performance scale and a verbal scale. The performance scale measures the ability to solve problems without the use of words, to think rapidly in visual images and to quickly interpret visual materials. The verbal subscale measures verbal comprehension, which includes applying verbal skills and information to the solution of problems
Currently IQ is calculated by estimating where, under the normal distribution curve, someone’s performance on an IQ test places him or her. The curve is standardized such that the mean score is 100 and the standard deviation around the mean is 15. An average IQ is therefore between 85 and 115. The scale will go from 55 to 145 (three standard deviations below and above the mean)
Intelligence quotient: a measure of a person's intelligence as indicated by an intelligence test; the ratio of a person's mental age to their chronological age (multiplied by 100)
If a child is shown to have a Mental age of 11 and is actually (chronological age) 9, the child would have an IQ = 122, in the higher than average range.
Hal, would probably excel at math skills and word definitions but fail on grammer, usage and comprehension. Just my take.
Let us know how your Hal fares!
