number of reader in a library are given below write the less than cumulative frequency table
Answers
Cumulative frequency is defined as a consecutive sum of frequencies.
The Cumulative frequency of first observation is the same as its frequency since there is no frequency before it.
Cumulative frequency distribution is of two types less than type and more than type.
SOLUTION:
Cumulative frequency distribution of the less than type:
In this question the number of students who have scored marks less than 10 are 7. The number of students who have scored marks less than 20 includes the number of students who have scored marks from 0-10 as well as the number of students have scored marks from 10 - 20.
Total number of students with marks less than 20 is 7+9= 16. Show the Cumulative frequency of the class 10 -20 is 16.
Similarly on computing the Cumulative frequency of the Other classes the number of students with marks less than 30, less than 40, less than 50, we get the distribution which is called the Cumulative frequency distribution of the less than type
CUMULATIVE FREQUENCY DISTRIBUTION OF THE LESS THAN TYPE IS IN THE ATTACHMENT.
