Relative Frequency
Relative Frequency: Relative frequency of a particular value of the variable or a class of values of the variable is obtained by dividing the frequency corresponding to that particular value or that particular class by the total number of observations in the data set, i.e., the total frequency.
Relative Frequency = 𝑓𝑟𝑒𝑞𝑢𝑒𝑛𝑐𝑦 𝑜𝑟 𝑐𝑙𝑎𝑠𝑠 𝑓𝑟𝑒𝑞𝑢𝑒𝑛𝑐𝑦/𝑡𝑜𝑡𝑎𝑙 𝑓𝑟𝑒𝑞𝑢𝑒𝑛𝑐𝑦
Relative frequency of any value or any class lies between 0 and 1. We calculate relative frequency if we want an idea about the relative importance of the particular value or class in relation to the total frequency.
