I hope my answer are right
The mode of the given data is 65.
Correct Question: Find the mode of the following distribution :
Classes : 0 - 20 20 – 40 40 – 60 60 – 80 80 – 100
Frequency: 10 8 12 16 4
Given:
Classes : 0 - 20 20 – 40 40 – 60 60 – 80 80 – 100
Frequency: 10 8 12 16 4
To Find:
The mode of the given data.
Solution:
The mode of any given data is found using the formula
, where 'l' is the lower boundary of the modal class, 'h' is the size of the modal class, is the frequency corresponding to the modal class, is the frequency preceding to the modal class, and is the frequency proceeding to the modal class.
In the given data, the class having maximum frequency is 60 – 80. So, , , , , and .
Substitute these values into the formula of mode.
Thus, the mode of the given data is 65.
