## Definition of Cumulative Frequency

Cumulative Frequency corresponding to a particular value is the sum
of all the frequencies up to and including that value.

Cumulative frequency is nothing but the running total of frequencies.

### Example of Cumulative Frequency

The cumulative frequency table represents the volcanic eruptions between 1900 and 2000.
As we see above, the cumulative frequency for the total number of
volcanic eruptions that took place in the years during 1920 - 40 is 12 + 15 = 27.
