Find the mode of the following distribution :
Classes : | 0-20 | 20-40 | 40-60 | 60-80 | 80-100 |
Frequency : | 10 | 8 | 12 | 16 | 4 |
The class having maximum frequency is the modal class.
The maximum frequency is 16 and hence the modal class = 60-80
Lower limit (l) of modal class = 60, class size (h) = 20
Frequency ( ) of the modal class = 16, frequency ( ) of class preceding the modal class = 12, frequency ( ) of class succeeding the modal class = 4.
