Question: The Canadian Institute for Health Information (CIHI) is a nonprofit organization that compiles data from a range of institutions-from governmental organizations to hospitals to universities. Among the many topics that interest public health specialists is the problem of low levels of organ donation. Medical advances have led to ever-increasing rates of transplantation, but organ donation has not kept up with medicine's ability to perform more sophisticated and more complicated surgeries. Data reported by CIHI (2005) provide Canadian transplantation and donation rates for 1994-2004. Here are the donor rates per million deaths.
a. Construct a time series plot from these data. Be sure to label and title your graph.
b. What story are these data telling?
c. If you worked in public health and were studying the likelihood that families would agree to donation, what research question might you ask about the possible reasons for the trend suggested by these data?
