Question

Explain when the median of a data set is a better measure of center than the mean.

Answer 1

The median would be a better measure of central tendency when the data is skewed (or if the frequency distribution for the data is skewed).

Answer 2

Sample Response: When there is an outlier in the data set, the dot plot or histogram will be skewed. In a skewed representation, the mean is pulled up or down toward the tail of the data. Therefore, skewed data affects the mean more than the median.
