For whole-number data, a sample distribution is often displayed in a table, as a set of values and their corresponding frequencies, or on an appropriate graph.

For measurement data, a sample distribution is often displayed in a table as a set of intervals of values (class intervals) and their corresponding frequencies, or on an appropriate graph.

For category data, a sample distribution is often displayed in a table as a set of categories and their corresponding frequencies, or on an appropriate graph.
