# Relative Frequency

A count of the number of occurrences of a data value in a sample, or the number of values falling within a fixed range, expressed as a proportion of the total number of observations. Data can be summarized in this manner by tabulating all the data values into distinct categories and then counting the number of times each category appears in the frequency distribution. This tabular summary is called a frequency table. A graphical representation would be a barchart or histogram.
