Yes and he knows the uslessness of point average in IQ. IQ is a range scoring. If you have an IQ of 115 that means that at the 97% confidence level using the Stanford Binet or the Weschler, your IQ has a plus or minus variation of up to 5 point...ie range of 110 to 120.
That is how IQs are discussed.
Also, IQ really should be broken down into it's different categories, verbal vs non-verbal, memory, processing speed.
My 10 year old daughter has brain damage, and her overall IQ on tests has varied from 89-100.
She has speech and auditory problems that bring down her IQ. However, she is a math whiz and routinely scores in the 95% (or higher) on math tests for kids her age.
My daughter routinely gets As & Bs in school (private Christian school) because she works hard. I know other kids don't have her problems, and they do not get as good of grades.
The other day she sang a song about herself she sang "I'm the girl that sets goals in my path and gets them." That is what makes her a winner compared to other kids.
