Q6 of 69 Page 6

Find the mode of the following distribution:

Here, the maximum class frequency is 28, and the class corresponding to this frequency is 30 – 40.


So, the modal class is 30 – 40.


Now, modal class = 30 – 40, lower limit (l) of modal class = 30, class size(h) = 10


frequency (f1) of the modal class = 28


frequency (f0) of class preceding the modal class = 25


frequency (f2) of class succeeding the modal class = 25


Now, let us substitute these values in the formula





= 30 + 5


= 35
