About this calculator
The range is the simplest measure of data spread — the difference between the largest and smallest values. It's easy to compute but extremely sensitive to outliers, so most statistics work uses standard deviation or interquartile range instead. Range is most useful as a quick sanity check of data extent.
Frequently asked
Because it depends only on the two extreme values. A single outlier completely changes the range. Standard deviation and IQR are more robust.
