Graphical calculation for mode, Applied Statistics

For calculating the mode of the grouped data graphically, the following procedure is adopted.

  1. Draw a histogram of the data; the modal class is the tallest rectangle.

  2. Draw a line from the top right corner of the tallest rectangle to the top right corner of the preceding rectangle.

  3. Draw a line from the top left corner of the tallest rectangle to the top left corner of the succeeding rectangle.

  4. Draw a line perpendicular to the X-axis from the point of intersection of lines drawn in steps 2 and 3. The point of intersection of the perpendicular line with the X-axis represents the mode.


    Let us calculate the Mode using the graphical method for the following distributions:

    Gross profits as percentage of sales








    Number of companies








    Using the procedure described above, we draw the histogram and other lines for the calculation of mode. The mode is 25.
