# What Do You Understand By Cumulative Frequency?

Commutative frequency is defined as a frequency of random value below a specific level. It just shows that how often the value of a random variable is different from a specific reference value. An example of cumulative frequency is as follows:

Example:
Frequency:     Cumulative frequency:
4   4
5   9 (4 + 5)
3   12 (4 + 5 + 3)
2   14 (4 + 5 + 3 + 2)
6   20 (4 + 5 + 3 + 2 + 6)
4   24 (4 + 5 + 3 + 2 + 6 + 4)

The total running of the frequencies is known as cumulative frequency. It is considered as a frequency of a random variable, which is usually below a specific level. It compares the value of a random value with the reference values. Cumulative frequency is represented on the cumulative frequency polygon. Given example will clarify the concept of cumulative frequency.

Example of Cumulative frequency

Frequency:     Cumulative frequency:

5   5
6   11 (5 + 6)
3   14 (5 + 6 + 3)
2   16 (5 + 6 + 3 + 2)
6   22 (5 + 6 + 3 + 2 + 6)
4   26 (5 + 6 + 3 + 2 + 6 + 4)
