In mathematics, the range is a concept which has various meanings in different topics:

The range of a function $f$ , also written as $\operatorname{ran}(f)$ or $\operatorname{Range}(f)$ , is the set of elements that the function outputs.
In statistics, the range is the difference between the lowest and highest values. For example. in {4, 6, 9, 3, 7}, the lowest value is 3, and the highest is 9, so the range is 9-3 = 6.
In some occasions, the term "range" can also refer to the mathematical concept of interval.
