a student's 10 scores on 10point class quizzes include a 6, a7, a4, five 9s, an 8, and a 10. The student claims that her average grade on quizze is 9 because most of her scores are 9s.

Ms. Sue,
Nope.
Find the mean or the average by adding all the scores and dividing by 10.

Ms. Sue,
Right! The average of the scores is 8.
9 is both the mode and the median.
