Statistics and Data Interpretation

While she couldn’t silence the guns of the Crimean War, Florence Nightingale, armed with 18,000 data points and a revolutionary diagram, proved with withering statistical clarity that the British soldier’s greatest enemy was not the Russian army, but the filth in his own barracks.
