  3. Data Source Description & Succinct Background • Alzheimer’s disease 7th leading cause of death across all ages in the US in 2006 and the 5th leading cause of death for those aged 65 and older. • Redesigned table based on information provided in: “Deaths: Final data for 2006.” (National Vital Statistics Reports Vol. 57, No. 14., Hyattsville, Md.: National Center for Health Statistics, 2009. by Heron, MP; Hoyert, DL; Murphy, SL; Xu, JQ; Kochanek, KD; Tejada-Vera, B.

  4. Original Table

  5. Reasons to Redesign • Too much information on the page: columns repeated twice on same page. • Unnecessary highlighting making it a bit more difficult to distinguish among states. • Not very easy to interpret data from table. • Not the best representation of this data.

  6. Improvements due to Redesign • Better representation of data: easier to single out extreme number of deaths due to the disease or extreme mortality rates. • Easier to interpret data. • Visualization option of all states that enables an easier way to distinguish among states with extreme mortality rates.

  7. Other potential Improvements • Inserting value labels on the last panel, values corresponding to the extreme cases. • Representing this data using other graphical methods.
