Discrete data

A set of data is said to be discrete if the values/observations belonging to it are distinct and separate, i.e. they can be counted (1,2,3,....).

Note 1: Examples include the number of patients in a doctor’s surgery; sex (male, female); blood group (O, A, B, AB).

Note 2: Discrete data is the counterfactual to continuous data
