Cumulative Frequency There are two types of cumulative frequency
The total frequencies of a particular class and all classes prior to that particular class is called the Less than type cumulative frequency of that class or simply the Cumulative frequency of that class. Example The marks of 30 students of a class, obtained in a test out of 75, are given below: 42, 21, 50, 37, 42, 37, 38, 42, 49, 52, 38, 53, 57, 47, 29, 59, 61, 33, 17, 17, 39, 44, 42, 39, 14, 7, 27, 19, 54, 51. A frequency table and a cumulative frequency table with equal class interval is formed. Directions: Answer the questions based on the table above. Also write at least one example of your own.
