What the Range Measures
The range is the simplest measure of dispersion in a data set. It is the difference between the largest value and the smallest value, showing how far apart the extreme values are. A larger range indicates greater spread, while a smaller range indicates the values are clustered more closely together.
How to Calculate the Range
To find the range, identify the maximum and minimum values in your data set and subtract the minimum from the maximum. The count is simply the number of valid values you entered.
- Range: Range = Maximum − Minimum
- Minimum: the smallest value in the data set
- Maximum: the largest value in the data set
Limitations of the Range
Because the range depends only on the two most extreme values, it is highly sensitive to outliers and ignores the distribution of the values in between. For a more complete picture of spread, consider also looking at the interquartile range, variance, or standard deviation.
