Can only have certain, distinct values
Is "counted"
Contains unconnected points
In mathematics, whole numbers, integers, and even integers are all
examples of discrete sets. These sets contain unconnected elements,
with gaps between each value.
In statistics, some data sets will be discrete. Examples of discrete data
sets are the number of adults in a household, the results of rolling two
,dice, and number of machines in operation, as these are distinct
groups.
(Looking at another set of data, consider the number of cars someone
owns. It is not possible to own 3.43.4 cars; you either own three cars or
four. The number of cars someone owns is an example of a discrete set
of data, since the values are distinct, separate, and unconnected.
Positive integers* are an example of discrete data.)
