Consider a relative frequency distribution table of hockey players with different heights. This table provides information about the fraction, or proportion, of data values under each class.

If this relative frequency is expressed in terms of percentage, it is called the percentage frequency distribution.

Suppose one is interested in the percentage of players with heights between 152 and 157 centimeters. To find out, multiply the corresponding relative frequency with 100 to get the percentage frequency. This indicates that 5 percent of players fall within the required height range.

Repeat the similar calculation for all the other relative frequencies to obtain the percentage frequencies under each class. Generally, the sum of all the percentage frequencies is equal to 100.
