Range

The **range** of a population or a sample of a population is a measure of spread. For data $x_i$, it is defined as

$\max(x_i) - \min(x_i)$

The range of a data set is sensitive to outliers? so is not considered a reliable measure.

In a spreadsheet, the formula to calculate the mean of a range is:

`=max(<range>) - min(<range>)`
