Answer :

This is a grouped frequency distribution table.

Notice the greatest number of students is 22.

Modal class = 20 – 25

Mode is given by Where,

L = Lower class limit of the modal class = 20

h = class interval of the modal class = 5

f1 = frequency of the modal class = 22

f0 = frequency of the class preceding the modal class = 16

f2 = frequency of the class succeeding the modal class = 11

Substituting values in the formula of mode,   Mode = 20 + 1.76

Mode = 21.76

Thus, mode is 21.76.
