What is a cumulative frequency?

Cumulative frequency, also known as cumulative frequency distribution, is a statistical concept used to analyze and describe data distribution in a dataset. It is a way to summarize and present the frequency of values or observations in a dataset in a tabular or graphical format.

Cumulative Frequency Formula

Formula to calculate cumulative frequency:

Cumulative Frequency (CF) = Cumulative Frequency of Previous Value + Frequency of the Current Value

How to calculate cumulative frequency?

To calculate the cumulative frequency for a given data set, you need to follow these steps:

  • Organize the data in ascending order.
  • Create a table with two columns: one for the data values and another for the cumulative frequency.
  • Starting with the first data value, the cumulative frequency for that value is the same as its frequency.

Solved Example

Example – Following dataset of exam scores for a class of 10 students:

Exam Scores: 72, 85, 64, 90, 78, 91, 76, 88, 70, 82


First, organize the data in ascending order:

64, 70, 72, 76, 78, 82, 85, 88, 90, 91

Create a table with three columns: The data value, frequency and cumulative frequency (CF).
