There's no getting away from statistics. We encounter them every day. We are all users of statistics whether we like it or not.

Do missed appointments really cost the NHS £1bn per year?

What's the difference between the mean gender pay gap and the median gender pay gap?

How can we work out if a claim that we use 42 billion single-use plastic straws per year in the UK is accurate?

What did the Vote Leave campaign's £350m bus really mean?

How can we tell if the headline 'Public pensions cost you £4,000 a year' is correct?

Does snow really cost the UK economy £1bn per day?

But how do we distinguish statistical fact from fiction? What can we do to decide whether a number, claim or news story is accurate? Without an understanding of data, we cannot truly understand what is going on in the world around us.

Written by Anthony Reuben, the BBC's first head of statistics, Statistical is an accessible and empowering guide to challenging the numbers all around us.
