Software defaults of graphing programs for depicting the "world's deepest" trash bin: The car company Volkswagen has sponsored a "fun theory" campaign in recent years in which ordinary behaviors are given game-like incentives to promote pro-social behaviors such as recycling or obeying the speed limit (http://www.thefuntheory.com/). In one example, Volkswagen created a seemingly super-deep trash bin; when a person would throw something out, a high-pitched whistling sound played for 7 seconds, culminating in a far-off-sounding room, as if the item had fallen for hundreds of feet! The fun-theory people collected data; in a single day, 72 kilograms of trash were thrown out in their "deep" bin, versus just 31 kilograms in a nearby trash bin.

a. Use a software program that produces graphs (e.g., Excel SPSS, Minitab) to bar graph for these data.

b. Play with the options available to you. List aspects of the bar graph that you are able to change to make your graph meet the guidelines listed in this chapter including the revised graph.
