Imagine you are a teacher and your students got the following
scores on a quiz you gave them: 8, 9, 8, 7, 10, 9, 6, 4, 9, 8, 7,
8, 10, 9, 8, 6, 9, 7, 8, 8. Place the scores in the table below

What is the goal of central tendency?
The goal of central tendency is to
find the “middle” of a distribution. It identifies one single
measure that best describes a set of data
