In the United States in 2002, there were 2,443,387 deaths of people of all ages. The following table lists the top 10 leading causes of death.
Cause of Death
Number of Deaths
|Malignant tumors (cancer)||
|Influenza and pneumonia||
Convert the number of deaths for each cause into a percentage of the total. Create a bar graph and a pie chart showing the percentage of all deaths in each category. Which type of graph appears more effective in conveying this information? See www.mathleague.com/help/data/data.htm (Math League Multimedia).
