Frequently asked questions
How is the median found?
Sort the numbers and take the middle one; with an even count, average the two middle values.
Why use the median?
It isn't skewed by outliers, so it represents the typical value better than the mean for lopsided data.
Median vs mean?
The median resists outliers, so it's often a fairer 'typical' value for skewed data.
