Mrs. McGee and Mr. Matthews are in charge of an after-school tutoring program for Fairview High School. Each teacher is in charge of supervising 10 students. They are comparing statistics for the two groups of students based on the hours tutored per week. Which statement is true?

b. The median for Mr. Matthews is greater than the median for Mrs. McGee.
c. The median for Mrs. McGee is greater than the median for Mr. Matthews.
d. The range for Mr. Matthews is less than the range for Mrs. McGee.

Answer 2

The median is when you line the numbers in order from least to greatest, then cross off doubles until you reach a number that you can't pair up (e.g. cross off the first and last numbers, second and second-to-last numbers, etc.).

Mrs. McGee: 5, 8, 10, 12, 14, 15, 16, 17, 18, 30
Mr. Matthews: 8, 11, 15, 18, 20, 22, 23, 25, 27, 33

Can you do it from here?
