Q. 134.7( 3 Votes )

Find the mode of the following distribution:


Answer :


Here, the maximum frequency is 25, and the class corresponding to this frequency is 40 - 50


So, the modal class is 40 – 50.


lower limit (l) of modal class = 40,


class size(h) = 10


frequency (f1) of the modal class = 25


frequency (f0) of class preceding the modal class = 12


frequency (f2) of class succeeding the modal class = 10


Now, let us substitute these values in the formula





= 40 + 4.64


Mode = 44.64(approx.)
