Böcker av David Spiegelhalter

Life is uncertain. We are all the result of an unforeseen and unforeseeable sequence of small occurrences. But what underlies this fragile chain of events? Is it random or just complex? And what role does luck play in our lives?David Spiegelhalter has spent his career crunching data in order to help understand uncertainty and assess the chances of what might happen. In The Art of Uncertainty, he gives readers a window onto how we can all do this better.Uncertainty, he argues, is a relationship between the observer and an object in the outside world. He shows us how we can express it numerically, and then update our beliefs about the future in the face of constantly changing experience. In crystal-clear prose, he takes us through the principles of probability, a field that informs everything from annuities to pandemics and climate change, while also examining the limitations of statistical modelling and arguing we need to have the humility to admit our ignorance.Drawing on a wide range of real-world examples, this is an essential guide to navigating uncertainty in a world that makes it inevitable

'I couldn't imagine a better guidebook for making sense of a tragic and momentous time in our lives. Covid by Numbers is comprehensive yet concise, impeccably clear and always humane' Tim HarfordHow many people have died because of COVID-19? Which countries have been hit hardest by the virus? What are the benefits and harms of different vaccines? How does COVID-19 compare to the Spanish flu? How have the lockdown measures affected the economy, mental health and crime?This year we have been bombarded by statistics - seven day rolling averages, rates of infection, excess deaths. Never have numbers been more central to our national conversation, and never has it been more important that we think about them clearly. In the media and in their Observer column, Professor Sir David Spiegelhalter and RSS Statistical Ambassador Anthony Masters have interpreted these statistics, offering a vital public service by giving us the tools we need to make sense of the virus for ourselves and holding the government to account.In Covid by Numbers, they crunch the data on a year like no other, exposing the leading misconceptions about the virus and the vaccine, and answering our essential questions. This timely, concise and approachable book offers a rare depth of insight into one of the greatest upheavals in history, and a trustworthy guide to these most uncertain of times.

A far from average book: the real story behind the statistics on risk, chance and choice.
