Cumulative Frequency Graph
A cumulative frequency histogram is a bar-based graphical depiction of a cumulative frequency distribution. It combines the features of a histogram with a cumulative frequency polygon. The following procedures will help you create a cumulative frequency histogram:
- Arrange Data: To begin, take a set of data and divide it up into class intervals.
- Compute Cumulative Frequencies: The cumulative frequency for each interval is the total of all the frequencies up to and including that interval.
- Build the Histogram: To build the Histogram, drawbars for each interval, where the height of the bar corresponds to the interval’s frequency.
- Create Cumulative Frequency Curve: Plot points for each interval beside the histogram, with the x-coordinate representing the interval’s upper-class boundary and the y-coordinate representing the cumulative frequency. To create a cumulative frequency curve, join these points.
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.
