Medical Specialty Optimization

I just bought a copy of Igor Pro (yay for grant money ^^), which is awesome for generating lovely graphics for publications -- I'm pretty new to the program, so I decided to wring some data through it in order to get more familiarized :)

First of all, the graph above shows the median annual incomes of physicians in different medical fields plotted against the years it takes to complete residency training (after med school). All this data is cobbled from Brian Freeman's Ultimate Guide To Choosing a Medical Specialty. If you'd like to see the data used for this graph, here it is:

List of medical specialties
List of medical specialties, sorted by median annual income
List of medical specialties, sorted by residency duration

Alternatively, here's an ASCII comma-separated version, if you'd like to import this data into SAS or whatever. Anyway, just as an interesting tidbit, the five highest-ranked specialties in terms of efficiency (maximize income, minimize years of residency) are:

1. Anesthesiology ($278,964, 4yrs)
2. Emergency Medicine ($204,519, 3yrs)
3. Orthopedic Surgery ($324,754, 5yrs)
4. Radiation Oncology ($303,750, 5yrs)
5. Opthamology ($240,265, 4yrs)

Bork bork bork!
