# Range

(1) In the theory of functions, the range is the set of all values that a function can take. (2) In data analysis, the range is the difference between the minimum and the maximum values of a data set.

Range is a high school-level concept that would be first encountered in a pre-calculus course covering functions. It is listed in the California State Standards for Algebra I.
