A range is an extent of values between its lower and upper bound. Examples include a DOM Range, the Ruby Range class, the Python range function, Perl 5's .. operator (in list context), Perl 6's Range Class and PostgreSQL's range types.

In statistics, range is the size of the smallest interval which contains all the data and provides an indication of statistical dispersion. It is measured in the same units as the data.
