A test score distribution has a mean of 8 and a standard deviation of 12. What is the shape of this distribution? Explain your answer.

What will be an ideal response?


Correct Answer:
This distribution must be positively skewed. The average distance of scores from the mean is 12. Because the scores cannot vary 12 points below the mean of 8, they must vary more than 12 points above the mean.
