A survey is conducted to determine whether
would prefer to work at home, if given the
20 office employees of a certain company
chance. The overall results are shown in the
first bar graph, and the results broken down
by gender are presented in the second.
a. Interpret the results of each graph.
b. Discuss the added value in including gen-
der in the second bar graph. (The second
bar graph in this problem is called a side
by side bar graph and is often used to
show results broken down by two or more
variables.)
c. Compare the side by side bar graph with
the two pie charts that you made for
