Find the mode of the following distribution.

Find the mode of the following distribution by drawing a histogram

Also state the modal class.

Solution:

Representing class on x-axis and frequency on the y-axis,
we draw a histogram as shown.
Join AB and CD intersecting each other at M.
From M, draw ML perpendicular to the x-axis.
L shows the mode which is 30.5 and class is 27-33.
