CASE PROBLEM 1: WENTWORTH MEDICAL CENTER
As part of a long-term study of individuals 65 years of age or older, sociologists and
physicians at the Wentworth Medical Center in upstate New York investigated the
relationship between geographic location and depression. A sample of 60 individuals,
all in reasonably good health, was selected; 20 individuals were residents of Florida,
20 were residents of New York, and 20 were residents of North Carolina. Each of the
individuals sampled was given a standardized test to measure depression. The data
collected follow; higher test scores indicate higher levels of depression. These data
are contained in the file Medical1.
A second part of the study considered the relationship between geographic location
and depression for individuals 65 years of age or older who had a chronic health
condition such as arthritis, hypertension, and/or heart ailment. A sample of 60
individuals with such conditions was identified. Again, 20 were residents of Florida, 20
were residents of New York, and 20 were residents of North Carolina. The levels of
depression recorded for this study follow. These data are contained in the file named
Medical2.

 

Managerial Report
1. Use descriptive statistics to summarize the data from the two studies. What
are your preliminary observations about the depression scores?
2. Use analysis of variance on both data sets. State the hypotheses being tested in
each case. What are your conclusions?
3. Use inferences about individual treatment means where appropriate. What
are your conclusions?
