A teacher is disappointed to find that most of her students' test scores are clustered together at the low end of the grading scale, with only a few students having high grades. If she was to graph the distribution, what shape would it have?
A) normal
B) positively skewed
C) negatively skewed
D) central
Answer: B
Rationale: A positively skewed distribution occurs when the long tail is on the right of the cluster. In this example, the students would be clustered together on the left of the graph, with an increasingly smaller tail of "good" students trailing off to the right.
