## Discrete variable

Variable like 1, 2, 3. Bond ratings are examples of discrete classifications.

## Discrete Random Variable

A variable that can take only one of several definite values. For example, one's FICO score is a discrete random variable because it can only be a positive integer between 300 and 850.
