Two students in a math class compared their scores on a series of five quizzes:
Student A Student B
4…………………….. 6
9…………………….. 5
3…………………….. 7
8…………………….. 5
9…………………….. 6
Considering the concepts of both central tendency and variability, find (a) which student tended to perform better on the quizzes and (b) which student tended to perform more consistently on quizzes.
