Answer :

The following steps must be followed to find the mode graphically.

1. Represent the given data in the form of a Histogram. The frequency determines the height of each bar. Identify the highest rectangle. This corresponds to the modal class of the series.

2. Join the top corners of the modal bar with the immediately next corners of the adjacent bars. The two lines must be cutting each other.

3. Let the point where the joining lines cut each other be 'A'. Draw a perpendicular line from point A onto the x-axis. The point 'P' where the perpendicular will meet the x-axis will give the mode.
