In mathematics, the term range has two primary definitions depending on whether you are working in statistics or algebra. In descriptive statistics, the range is the difference between the highest and lowest values in a dataset, serving as a basic measure of variability. In algebra, the range of a function refers to the complete set of all possible output values that result from substituting every valid input value (the domain) into the function. Both concepts are essential for analyzing mathematical relationships, understanding data sets, and studying functions in calculus and pre-calculus.
