When you’re in a medical emergency, you don’t typically think of calling a statistician.

However, the COVID-19 outbreak has shown just how necessary a clear understanding of data and modelling is to help prevent the spread of disease.

One person understood this a long time ago. Were she alive today, Florence Nightingale would understand the importance of data in dealing with a public health emergency.

Nightingale is renowned for her career in nursing, but less well known for her pioneering work in medical statistics. But it was actually her statistical skills that led to Nightingale saving many more lives.
