Example of Domain of Variable
Let $C$ be a country in Europe.
The domain of $C$ is the set $\set {\text {France}, \text {Germany}, \text {Spain}, \text {Italy}, \ldots}$
These can be represented numerically if desired, by assigning an integer to each of the countries in Europe, for example:
- $1: \text {France}$
- $2: \text {Germany}$
- $3: \text {Spain}$
- $4: \text {Italy}$
- $\vdots$
$C$ is a discrete variable.
