Frequently asked questions
Is range the same as spread?
Range is the simplest spread measure: just the max minus the min of the data.
Does order matter?
No. The tool finds the maximum and minimum regardless of the order you enter.
Why does an outlier change it so much?
Statistics like the mean and range respond directly to extreme values; the median is more stable, which is why both are shown where relevant.
