  1. Philadelphia versus MontgomeryAIDS Comparison Tinamarie, billy, Richard and Tori

  2. Overview Two data sets: Philadelphia and Montgomery county Comparison of living AIDS cases by age group for the year 2003

  3. The Data The data was collected by the Pennsylvania Department of Health These include cases reported as of 06/30/2004 (these were the most recent we could find)

  4. Frequency Distributionsour raw data was already in a frequency distribution Pennsylvania Ages Frequency 0-12 195 13-19 120 20-29 2,295 30-39 6,270 40-49 4,220 Over 49 1,502 Philadelphia County Ages Frequency 0-12 137 13-19 74 20-29 1,403 30-39 3,657 40-49 2,426 Over 49 956 Montgomery County Ages Frequency 0-12 3 13-19 1 20-29 49 30-39 126 40-49 94 49+ 38

  5. Box Plots

  6. Histogramsthe curve would be considered slightly skewed to the left

  7. Individual Data overview Montgomery The graphs show that the distribution of AIDS cases was similar for both counties.

  8. The State of Pennsylvania The pie graph shows that most of the cases were ages 30-39. If we compare this to the counties, the distribution of cases per age group is similar although much more people are involved.

  9. CVDOT • Measures of center • Mean • Philadelphia = total of 8,653 people living with aids with a Mean age = 37.9 (38) • Montgomery = total of 311 people living with aids. Mean age 38.7 (39) • The entire state of PA = Mean age 37.9 (38) • Median: ( age) • Philadelphia: 32.45 • Montgomery :33.02 • State of PA: 32.93 • Mode = 34.5 • BMC = The best measure of center for these data sets is mostly likely the median because our data may have had a few outliers. • Philadelphia z score • 49 - 37.9 / 44.7 = 0.248 • 0 - 37.9 / 44.7 = - 0.848 • Montgomery county z score: • 49 - 38.7 / 44.7 = 0.230 • 0 - 38.7 / 44.7 = 0.866

  10. Variance • Variance • Standard Deviation: 44.7 • Range = 54 for all * A large number of our calculations are estimates due to the fact that our data set was given in a frequency distribution and was not individual data values.

  11. Interpretation & Conclusions • From our data we can assume the following: • The majority of AIDS cases for both counties are within the age range of 30-39. • Philadelphia county has more AIDS cases than Montgomery County. • Both counties seem to have a similar distribution of AIDS cases in each age group.

  12. Explanations & Connections • Numerous explanations for the results exist. • 1. The fact that the county of Philadelphia is double the size of Montgomery county accounts for some of the large difference in the number of AIDS cases but Philadelphia has double the people yet still has 26 times more AIDS cases. • 2. Philadelphia is a major city in the USA with areas of extreme poverty, along with immigrants from other countries. • When looking at the age groups, we notice the category of people age 30-39 had the most number of AIDS cases. The reasons for this may include: • these individuals may have lacked AIDS education when they were in high school/college because of the time period when AIDS was a new epidemic. • It takes time for the first signs of HIV/AIDS to develop and these individuals probably contracted the virus during their 20s when risky behavior was more likely.
