The formula to calculate relative frequency is:
\[ \text{Relative Frequency} = \frac{\text{Frequency of a specific value}}{\text{Total number of observations}} \]
Relative frequency is the ratio of the number of times a specific value occurs to the total number of observations. It helps in understanding the proportion of each value in the data set.
Consider the data set [2, 3, 3, 4, 4, 4, 5, 5, 5, 5]:
