To determine which kind of graph can display the given data in the best way.

Answer to Problem 3E
Double bar graph
Explanation of Solution
Given:The number of boys and the number of girls participating in annual volunteer program is to be compared from 1995 to present.
Double bar graph will be used here because we have to compare number of boys and number of girls attending the volunteer program the given period of time. For the given period of time, there may be big changes in the data because given period of time is long. And so one should use here Double bar graph. We can easily compare the numbers by just looking at the length of the bars and draw the required conclusions.
