Find the mode of the following distribution:

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.)
