A frequency or relative frequency table is used to summarize categorical, nominal, and ordinal data. Count the number of observations that fall into each mutually exclusive category. The number associated with each category is called the frequency and the collection of frequencies over all categories gives the frequency distribution of that ...

The number associated with each category is called the frequency and the collection of frequencies over all categories gives the frequency distribution of that variable. The relative frequency is a number which describes the proportion of observations falling in a given category. Instead of counts, we report relative frequencies or percentages.
