In statistics, if we have a set of observations expressed in numbers (for example, lengths of trees in meters, weights of animals in kilograms and so on), then the difference between maximum and minimum is called range.

Range is useful if data is distributed more or less uniformly (between the minimum and the maximum).

For periodic functions, half of the difference between maximum and minimum is called amplitude. For example, the function `f(x)=1+2sin(x)`  has the amplitude `2,` while its maximum is `3,` its minimum is  `-1` and their difference is `4.`
