Most people mistake the median, or Q2, for the mean.

For example, a teacher gives a 10 point test and says that the average (mean) score is a 7.She says your score is at the 50th percentile, but you didn't get a 7 on the test.How is this possible?

Part A:Give me a set of numbers whose mean and median (Q2) arethe same.Be sure to state what the mean and median are for your example.

Part B:Give me another set of numbers whose mean and median (Q2)are NOT the same.Be sure to state what the mean and median are for your example.
