FAQ
Frequently asked questions
What does range measure?
How spread out a dataset is, from its smallest to largest value.
Is range affected by outliers?
Yes, heavily — a single extreme value can dramatically change the range.
What is the range of a single number?
0, since the maximum and minimum are the same.
How is range different from standard deviation?
Range only looks at the two extreme values; standard deviation accounts for every value's distance from the mean.
