Examples of Discrete Variables
Number of Children
The number $N$ of children in any given family can take one of the values in the set $\N = \set {0, 1, 2, \ldots}$
However, $N$ cannot take the value of a number which is not a natural number, for example, $2 \cdotp 5$ or $3 \cdotp 842$.
That is, $N$ is a discrete variable.
