How to Find Cumulative Frequency?
Cumulative frequency(cf) is defined as the frequency of the first-class interval is added to the frequency of the second class, and this sum is added to the third class. Cumulative frequency is the total of a frequency and all frequencies in a frequency distribution until a certain defined class interval.
Solved Example:
Find the cumulative frequency of the data set
Month Number of toy cars sold (Frequency)
January 20
February 30
March 15
April 18
Solution:
Given: Data set = {20, 30, 15, 18}
Month Number of toy cars sold (Frequency) Total number of toy cars sold (Cumulative Frequency)
January 20 20
February 30 20 + 30 = 50
March 15 50 + 15 = 65
April 18 65 + 18 = 83
Therefore, cumulative frequency is {20, 50, 65, 83}
Similarly, you can try the calculator to find the cumulative frequency for the given data set:
a) {14, 15, 21, 7, 8, 16, 4, 5} b) {18, 25, 30, 16, 19, 22, 17}
