Learning Objective
I can describe how outliers affect the mean and range of a data set.
- 1
The mean uses all of the data in a set, but it is easily influenced by outliers.
- 2
The median is the middle value in a sorted data set, and it is the best measure of central tendency to report when there are outliers.
- 3
The mode is the value that occurs most frequently, but it is not robust because small changes in frequency can easily affect it.
