## Introduction

The frequency distribution is a representation that shows the number of observations within a given interval, in either a graphical or a tabular format. The size of the interval depends on the analysed data and the analyser's goals. The intervals have to be exhaustive and mutually exclusive. Usually, frequency distributions are used in a statistical sense. In general, the distribution of frequencies can be associated with a normal distribution chart.

## Understanding

A frequency distribution, as a statistical method, provides a visual representation for the distribution of observations within a given study. Analysts also use the distribution of frequencies to display or explain the data obtained in a sample.

For starters, children's heights may be divided into many different categories or ranges. Some are tall when calculating the height of 50 children, some are low, but there is a high chance of a higher frequency or concentration in the middle range. The key criteria for data collection are that the intervals used do not overlap and must include all possible observations.
