A percentage frequency distribution, in general, is a display of data that indicates the percentage of observations for each data point or grouping of data points. It is a commonly used method for expressing the relative frequency of survey responses and other data. The percentage frequency distributions are often displayed as bar graphs, pie charts, or tables.
The process of making a percentage frequency distribution involves the following few steps: note the total number of observations; count the total number of observations within each data point or grouping of data points; and finally, divide the total observations within each data point or grouping of data points by the total number of observations. However, it is to be noted that whenever the percentage frequencies are used in the relative frequency distribution, it is also sometimes termed as percentage frequency distribution.
