Cumulative Frequency Polygon
A graphical depiction of the cumulative frequencies in a dataset is called a cumulative frequency polygon. Plotting points that reflect the cumulative frequencies at the upper-class borders of the intervals in a grouped dataset and joining these points by line segment results in this polygon.
The cumulative frequency polygon can also be created in two ways
- Less than cumulative frequency polygon
- More than cumulative frequency polygon
Note: The only difference between a Cumulative Frequency Curve and a Cumulative Frequency Polygon is that the curve is drawn freehand and in a polygon line segments are used to connect the plotted coordinates.

Cumulative Frequency
Cumulative Frequency: In statistics, cumulative frequency is defined as the sum of frequencies distributed across various class intervals. This involves organizing the data and their totals into a table where the frequencies are allocated according to each class interval.
In this article, we will cover a thorough explanation of cumulative frequency, cumulative frequency curve, formula, and a few examples based on it for better understanding.
