==Key Stage 4==
===Meaning===
A '''discrete variable''' is a variable which can only be specific values with no numbers in between.
===About Discrete Variables===
: '''Discrete variables''' are often [[integer]]s, 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|boiling point]] of an [[alkane]] depending on the number of [[Carbon]] [[atom]]s in that [[alkane]]: The number of [[Carbon]] [[atom]]s 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.
