Concept

In statistics, frequency describes how many times a specific value, range of values, or category appears in a data set, which helps to summarize and analyze the data distribution. Consider the following data set containing the ages of ten junior high school students.

Ages of Ten Junior High School Students | ||||
---|---|---|---|---|

$12$ | $13$ | $13$ | $14$ | $13$ |

$14$ | $12$ | $15$ | $12$ | $14$ |

In this data set, the age $13$ appears $3$ times, so its frequency is $3.$ This type of frequency is also called the **absolute frequency**.
