Definition:Relative Frequency

Definition
Let $S$ be a sample or a finite population.

Let $\omega$ be a qualitative variable, or a class of a quantitative variable.

The relative frequency of $\omega$ is defined as:


 * $\operatorname{RF}\left({\omega}\right) := \dfrac {f_{\omega}}{n}$

where:


 * $f_{\omega}$ is the frequency of $\omega$


 * $n$ is the number of individuals in $S$.

See Relative Frequency Model for this concept in the context of Probability Theory.
