#### Concept Quizzes

Mr. Jones and Ms. Smith each teach a Calculus class at a local high school. Each of their students take a county-mandated final exam at the end of the year. Ms. Smith plots both of their average scores in the graph above. Is there anything that makes the graph misleading or unclear?

Mr. Jones is not pleased with Ms. Smith for how often she rubs in her better average. He therefore decides to make the above visual that represents his and her class size. He has a class size of 20, and she has a class-size of 10. Is his visual misleading or unclear?
