Cumulative Frequency Formula
The frequencies of all the data points that are equal to or less than a given value are added up to determine the cumulative frequency (CF) at that particular data point. In terms of math, it is expressed as:
[Tex]CF_i = \sum_{j=1}^{i} f_j [/Tex]
where,
- CFi is Cumulative Frequency at the ith Data Point
- Fj is the jth Data Point’s Frequency
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.
