Uses applied statistics to disprove the medical sssumptions of her day.
Using fatality counts from the Crimean War, Nightingale develops a
progressive series of statistical diagrams that reveal startling
information: most soldiers did not die of their wounds, as reported, but in
army hospitals, from diseases related to poor hygiene. When futher data
show army death rates twice that of the civilian population, Nightingale
traces the cause to overcrowded, disease-riodden barracks.
