ISEE Upper Level Reading Comprehension Flashcards: Supporting Evidence

 The author argues that Florence Nightingale’s impact on medicine came as much from statistics as from bedside care. While she is often remembered for nursing wounded soldiers during the Crimean War (1853–1856), the author concludes that her most lasting contribution was persuading governments to reform sanitation through data. The passage explains that poor ventilation, contaminated water, and overcrowding caused preventable deaths in military hospitals.

 The author cites Nightingale’s reports to British officials after the war, which included carefully organized mortality figures. She used visual charts, including the famous “coxcomb” diagrams, to show that disease killed far more soldiers than battlefield injuries. Secondary historians quoted in the passage argue that these clear comparisons made it difficult for policymakers to ignore the problem. As reforms were implemented, hospital death rates declined, supporting the author’s claim that data-driven advocacy produced measurable change.

 The passage also notes that Nightingale’s approach influenced later public health efforts. By treating sanitation as a matter of evidence and administration, she helped establish a model for reforms that could be evaluated. Therefore, the author concludes that Nightingale should be understood as a pioneer of applied statistics in service of human welfare.
