Introduction:
A Frequency Distribution defines us a summarized accumulation of data divided into commonly exclusive classes and the number of appearance in a class. Example: To show election result, income of people for a certain region, sales of a product within a certain period, student loan amounts of graduates, etc. Some of the graphs can be used with frequency distributions are histograms, line graphs, bar charts and pie charts.
Types of Frequency Distribution:
An ungrouped frequency distribution simply lists the data values with the corresponding number of times or frequency count with which each value occurs.
A grouped frequency distribution is obtained by constructing classes (or intervals) for the data, and then listing the corresponding number of values (frequency count) in each interval.
