Graphic Location of Mode
Since mode is a positional average it can be located graphically by the following process:
- A histogram of the frequency distribution is drawn.
- In the histogram, the highest rectangle represents the model class.
- The top left corner of the highest rectangle is joined with the top left corner of the following rectangle and the top right corner of the highest rectangle is joined with the top right corner of the preceding rectangle respectively.
- From the point of intersection of both the lines a perpendicular is drawn on the X-axis, and check that point on the X-axis. This will be the required value of mode.
