Discrete Random Variable 

A variable that takes on only a finite or countably infinite number of values.

(Wooldridge 2006, 729)


Countably infinite means that even though an infinite number of values can be taken on by a random variable, those values can be put in a one-to-one correspondence with the positive integers.
