¹ Total number of murders for which supplemental homicide data were received.

²Pushed is included in hands, fists, feet, etc.

³ Limited supplemental homicide data were received.

(FBI, 2011)

The table above for murders by weapon types is from the FBI’s Criminal Justice Services Division and represents the reported murders in each state for the year 2011. (Please see http://www.fbi.gov/about-us/cjis/ucr/crime-in-the-u.s/2011/crime-in-the-u.s.-2011/tables/table-20 for the referenced table.)

Complete the following and insert the required responses and descriptions in a Word document. Submit your Word documents in the Unit 5 IP Submissions area.

From the data in the table above, using the top 7 states for number of murders, construct a table showing the number of murders by each category of firearms.
From the data in the table above, using the top 7 states for number of murders, construct a pie chart representing the number of murders in each state committed with handguns; use percentages to make sure that the pie chart is correctly proportioned.
From the data in the table above, using the top 7 states for number of murders, construct a bar chart representing the number of murders in each state committed with handguns; use percentages to make sure that the bar chart is correctly proportioned.
From the data in the table above using the top 7 states for number of murders, construct an area chart representing the number of murders in each state committed with handguns; use actual numerical values and make sure the area chart is correctly proportioned.
Which of these three chart types do you think gives the most useful visual information about the data represented?
Is there another chart type that you think would better represent these data? Why or why not?
