Types of Cumulative Frequency
Cumulative Frequency are classified into two types namely:
- Less than Cumulative Frequency
- More than Cumulative Frequency
Less than Cumulative Frequency
Less than cumulative frequency, also known as a less than ogive, is a rising curve. It is obtained by adding the first-class frequency to the second-class frequency, and so on. Here, the cumulate begins from the lowest to the highest class.
In this frequency curve, the points are plotted using upper limits (x-axis) and their corresponding cumulative frequency (y-axis).
More than Cumulative Frequency
More than cumulative frequency, also known as a greater than cumulative frequency, is a downward curve. It is obtained by determining the cumulative total frequencies starting from the last class to the first class. Here, the cumulate begins from the highest to the lowest class.
In this frequency curve, the points are plotted using lower limits (x-axis) and their corresponding cumulative frequency (y-axis).
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.
