Range Calculator (Statistics)
Find the statistical range (max − min) of a dataset with extremes identified.
Inputs
Range
11.0000
Minimum
3.0000
Maximum
14.0000
Step by step
Values used
Data (comma separated) = 12, 7, 3, 14, 9
Formula applied
Range = max(x) − min(x)
Range
= 11.0000
Minimum
= 3.0000
Maximum
= 14.0000
How it works
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
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.
