Likelihood of Cancer
Julie A. Ellsworth
Truckee Meadows Community College
In this module students will determine the likelihood of developing cancer by examining various data.
They will be presented with two pie charts, one showing the leading
cause of death in the United States for people ages 10-24 and one for people ages 25 and
older (pie chart data for 33 individual states are also available on line). Students will
examine the national data and answer a series of questions designed to help them
understand and compare the two charts. Secondly, they will be presented with cancer incident
data for two different age groups to compare with the pie chart data and to investigate the
likelihood of developing different types of cancer at different ages (other datasets can be
generated using the DEVCAN database of cancer data available on line).
The mathematics involved is reading and interpreting pie charts; calculating and understanding
percentages and proportions.
