Frustration Disclaimer

• The data presented in this presentation is
  incomplete
• Collected data was on two floppy disks, one
  containing preliminary data, and another
  containing more data and the final project. This
  second disk was infected with and virus..and all
  data was corrupted.
• The data sets salvaged from the first disk are
  from 2004 and 2000

3
Purpose

• The purpose of this project was to examine both
  the average difference between the life
  expectancies of males and females and how these
  spans have changed over the past 54 years.
• Only citizens of the Louisville, Ky area were
  used in this study

4
Hypothesis

• I expect to find that women have longer lives on
  average than men.
• The average life expectancy for both genders will
  have increased over the course of time.

5
Methods

• Data was collected by examining obituaries and
  collecting data about age at the time of death.
• Recent deaths were taken from the Courier Journal
  website.
• Older data (beyond the past year) was collected
  by examining news papers on microfilm at the
  public library.

6

• For each year examined, 15 male ages and 15
  female ages for each month of that year were
  recorded in a spreadsheet.
• The male and female values were then averaged.
• The monthly averages were then averaged again to
  obtain a yearly mean.
• The male and female yearly means were then
  compared.

  year span.
