Consider a frequency distribution table with different heights listed in the first column and the number of hockey players for each class listed in the second column. The sum of the frequency values represents the total number of players in the sample. A relative frequency distribution gives the ratio of the number of players under each class to the total number of players. For example, for the first class, dividing the frequency by the sum of all the frequencies gives the relative frequency of 0.05. Similarly, the relative frequencies for each class are calculated and listed in the third column. Note that the sum of all relative frequencies must be close to one. Relative frequency is helpful to identify how common the value is in the data set.
