About Discrete Variables

Discrete variables are often integers, but not always.

Examples

The number of people with a particular eye colour: The number of people is a discrete variable because you can't have half a person.
The boiling point of an alkane depending on the number of Carbon atoms in that alkane: The number of Carbon atoms is a discrete variable because you can't have half an atom.
How the shoe size depends on the size of people's feet: The shoe size is a discrete variable because there are no sizes between 7 and 7.5.
