Question:

The Rock and Roll Hall of Fame is located in Cleveland, Ohio. Every year since 1986, an induction ceremony has been held at the Rock and Roll Hall of Fame, and there are presently 343 inductees in the Rock and Roll Hall of Fame. Each inductee belongs to one of four categories: Performers, Non-performers, Musical Excellence, and Early Influences.

a) Suppose we only want to look at the performers who have been inducted into the Rock and Roll Hall of Fame. Specifically, for each performer, we determine the number of top 50 hits the performer had. If we do this for all 242 performers in the Rock and Roll Hall of Fame and then want to display the “number of top 50 hits,” what type of graphical display would you recommend be created, and why?

b) On the homepage for the Rock and Roll Hall of Fame, the following message is posted, along with a link to a survey. The survey is intended to be completed by individuals who actually visit the Rock and Roll Hall of Fame in Cleveland.

As you think back to what you learned earlier in the semester, what would we call this type of sampling method?

c) Suppose the survey mentioned above includes a question about the reason for visiting the Rock and Roll Hall of Fame. Individuals can choose among multiple reasons, and they can choose more than one reason for visiting the Rock and Roll Hall of Fame. If we ultimately want to create a graphical display that presents the percentage of individuals who choose each reason, would it be better to create a bar graph or a pie chart, or would either graphing method be equally appropriate? Please explain.
