Question

In a percentage bar graph, all bars are of height ________ .

• A. 50 units
• B. 100 units
• C. 1000 units
• D. 500 units

Answer 1

The correct option is B 100 units

In a percentage bar graph, all bars are of height 100 units.
To draw a sub-divided bar graph on a percentage basis, we express each component as the percentage of its respective total.

In drawing a percentage bar graph, bars of length equal to 100 units for each class are drawn first.

It is then sub-divided into the proportion of the percentage of their component in the second step.

The diagram so obtained is called a percentage bar graph. Following is an example of percentage bar graph.
