What is Cumulative Frequency?
Cumulative Frequency is the sum of all previous frequencies of the given data. Consider the frequency of the first class interval plus the frequency of the second class interval, the sum is then added to the frequency of the third class interval, and so on, to get the cumulative frequency. Therefore, the cumulative frequency table, also known as the cumulative frequency distribution, is the table that shows the cumulative frequencies that are split over various classes.
In most cases, the number of observations in the given data set that fall above or below a specific frequency is determined using the cumulative frequency distribution.
Cumulative Frequency Meaning
Cumulative frequency (c.f.) is the term used to determine the total number of observation above the current point, irrespective of the class of the given dataset. In simple terms, it is the sum of all previous observation of the given data.
Cumulative frequency is classified into two types: lesser than type and greater than type. The number of observations in a given data set that fall above (or below) a specific frequency is determined using cumulative 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.
