The relative frequency of any given data value can be calculated by dividing its frequency by the total frequency of the given set of data values. An item’s relative frequency is defined as a fraction indicating how frequently it appears in comparison to all other things.
Enter a set of data values in the calculator below. The calculator then arranges the data in the form of a frequency distribution table which shows both the frequency and relative frequency of the given data values.
For example, suppose we enter the following data values: 22, 22, 34, 34, 55.
Then the relative frequency distribution is given as,
|Value||Frequency (f)||Relative Frequency (=f/N)|
|22||2||2/5 = 0.4|
|34||2||2/5 = 0.4|
|55||1||1/5 = 0.2|
|TOTAL||N = 5|
The relative frequency of an item and all prior data points are added together to form the cumulative relative frequency.
