This optional question was not popularly answered by the candidates. Many of the candidates who attempted it did not know how to draw a divergent bar graph. They were expected to obtain the mean and calculate the deviations from the mean as follows:

Divergent bar graph
           Average of the contributions = $50,000         
           Country A:        $35,000-$50,000=       -$15,000        
           Country B:        $60,000-$50,000=       +$10,000
           Country C:        $45,000-$50,000=          -$5,000        
           Country D:        $80,000-$50,000=       +$30,000        

Uses of divergent bar graph
-for summarizing large amount of data in visual form
-for presenting data in graphical form.
-for plotting climatic data
-to show the economic performance of an enterprise over the years
-to show the performance of a sector within an economy
-to make data more meaningful and vivid
-for inter-regional comparison on similar items
-for showing the status of some social economic variable of a country
-to show deviation of data from a common mean
-to present data in attractive and more mind engaging form
