What is the average scaled score on CTOPP-2 subtests with mean 10 and standard deviation 3?

Explanation:
Scaled scores on the CTOPP-2 are set up with a fixed mean of 10 and a standard deviation of 3. The average, by definition, is the mean, so the typical score is 10. The other numbers would place a score above or below the mean by some portion of the SD (for example, 12 is about 0.67 SD above the mean, 14 about 1.33 SD above, and 8 about 0.67 SD below). So the best answer is 10.
