**Frequency **is the number of occurrences of something that has happened. The frequency of a particular observation tells us how many times that observation has occurred in the data.

In statistics **frequency
distribution** is a table or plot which shows the frequency of different
observations in given data or sample.

**Example: **The
score of a football team in last matches played in the last week is given
below:

**1, 4, 2, 2, 3, 1, 1,
0, 3, 5, 4, 2, 3, 3**

- To plot frequency distribution table firstly, put the numbers in order:

0, 1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 5

- It shows that 1 occurred 3 times, 2 also occurred times. Etc.
- Now plot the table.

Score | Frequency |
---|---|

0 | 1 |

1 | 3 |

2 | 3 |

3 | 4 |

4 | 2 |

5 | 1 |

From the table we can clearly see that:

- The team scored 0 in one match.
- 3 goals happened most.
- Only once the team scored 5 goals.
