A frequency distribution is a visualization of the number of observations within a certain interval that can be either graphical or tabular in nature. The distribution is the pattern of the variable’s frequency, whereas the frequency is how frequently a value occurs within an interval.

The interval size is determined by the analysis objectives and the data being examined. The intervals must be exhaustive and mutually exclusive. Statistical applications of frequency distributions are common. Frequency distributions can typically be visualized on a normal distribution chart.

A frequency distribution, used as a statistical tool, offers a visual depiction of the distribution of observations within a specific test. Frequency distributions are frequently used by analysts to represent or visualize the data gathered from a sample. Children’s height, for instance, can be divided into a number of distinct categories or ranges.

Although some of the 50 youngsters whose heights were measured were tall and some were small, there was almost certainly a higher frequency or concentration in the medium range. The periods chosen must not overlap and must include all potential observations; these are the two most crucial requirements for data collection.
