Range Calculator (Statistics)
Find the statistical range (max − min) of a dataset with extremes identified.
About Range Calculator (Statistics)
The range is the simplest measure of dispersion: the difference between the largest and smallest values in a dataset. While easy to compute, it is sensitive to outliers.
Formula
Range = max(x) − min(x)
- x
- Dataset values
Worked example
With the default values below, Range Calculator (Statistics) returns Range of 11.0000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the single input listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
Why is range considered a weak measure of spread?
It only uses two data points (the extremes) and ignores the distribution of all other values, making it very sensitive to outliers.
What are better alternatives to the range?
The interquartile range (IQR), variance, and standard deviation are more robust measures because they consider more data points.
