What was the mean score?
A college professor conducted student evaluations at the end of a semester. One important question asked was, “Would you recommend this professor to a friend?” Fifty-four students responded using the following 1-to-5 rating scale.
1 = “absolutely not”
2 = “probably not”
3 = “no opinion”
4 = “probably yes”
5 = “absolutely yes”
Student responses were recorded. “Blank” indicates that a student skipped this question on the evaluation.
