More Or Less: Behind The Stats

How can we use statistics to predict how many medals each nation will win? We speak to Dr Julia Bredtmann, an economist at the RWI Leibniz Institute for Economic Research. She has come up with a model to predict how many medals each country will win, along with her colleagues, Sebastian Otten, also from the Leibniz Institute, and Carsten Crede of the University of East Anglia.Some countries like the US and China have a large population and GDP, but a number of countries do very well for their size and wealth. Julia explains the different factors you have to consider to predict Olympic success.

The Government says that since the introduction of the 5p fee for single use plastic bags their use has plummeted. We take a look at the numbers.Olympic Medals at Rio 2016 The Olympic Games are with us again. So how can we use statistics to predict how many medals each nation will win? We speak to Dr Julia Bredtmann, an economist at the Leibniz Institute for Economic Research.Income inequality Politicians and commentators often claim that the rich are getting richer while the poor are getting poorer. But what do the numbers actually tell us about income inequality in the UK? Tim Harford interviews Jonathan Cribb of the Institute for Fiscal Studies, the co- author of a comprehensive analysis of Living Standards, Income Inequality and Poverty in the UK.Desk of Good News – Maternal mortality rates The number of women dying in childbirth is falling around the world. In 1990, maternal mortality rates were 385 deaths per 100,000 live births Today there are 216 deaths per 100,000 live births. This means the death r

How can the techniques of computer science help us in everyday life? We speak to Brian Christian co-author of ‘Algorithms to Live by: The Computer Science of Human Decisions’. He argues that the techniques of computer science can help us manage everyday situations in a more logical and efficient manner. So which algorithm can help solve the problem of odd socks? And what is the most efficient way of alphabetising your book collection? Tim Harford investigates.

Many news outlets have reported this week that a Waitrose supermarket pushes up house prices in the surrounding area. It’s based on research that also suggests that other supermarkets have a similar but smaller effect. We take a highly sceptical look at the correlation.Statistics and the EU referendum campaign We look at how the two campaigns, the media, and the much-discussed “experts” used statistics during the EU referendum campaign. Tim Harford interviews Will Moy, director of Fullfact, and Paul Johnson, director of the Institute for Fiscal Studies.Antiques Roadshow BBC One’s Antiques Roadshow is a hugely popular television programme, where experts examine and value antiques and collectables. We ask whether the items featured really jump in value, or are we just seeing the price tag rise over the centuries in line with inflation? More Or Less reporter Charlotte McDonald heads down to the show to find out.Computer Science and Socks Tim Harford speaks to Brian Christian, co-author of ‘Algorithms to Live by:

The Irish Central Statistics Office has released figures showing that Ireland’s economy grew by 26% in 2015. That would make it the fastest growing economy in the world. But American economist Paul Krugman described this as “leprechaun economics” as this growth rate is so unrealistically high. More or Less explores how multinational companies with headquarters in Ireland have led to an accounting headache for working out the country’s GDP.Also, the mobile gaming app Pokemon Go has taken the US by storm and is now spreading across the world. But does Pokemon Go really have 26 million daily active users in the US? More Or Less investigates.

Protests have spread across the United States over the last few weeks. The protestors have been registering their feelings about incidents where police have shot and killed black men. High profile recent incidents resulted in the deaths of Alton Sterling and Philando Castle, and the protestors feel that minorities are being disproportionately targeted by the police.On top of this, at a recent protest in Dallas a gunman shot and killed five police officers.But what can the numbers tell us about the issue? How many people do police officers kill each year in the USA? And how many police officers are killed? Tim Harford investigates.Producers: Charlotte McDonald, Elizabeth Cassin

It’s often said that we should all be aiming to get eight hours of sleep a night. But could it actually lead you to an early grave? Research shows that sleeping for longer, or shorter, than average is associated with an increased risk of disease and mortality. But what’s causing the health problems, and should you really give up the lie-in? Ruth Alexander looks at the latest sleep science with Dr Gregg Jacobs from UMASS Medical Center, US; Professor Franco Cappuccio from Warwick University, UK; Professor Jim Horne of Loughborough University, UK; and Professor Shawn Youngstedt of Arizona State University, US. *Please note this is a repeat from February 2015*(Photo: Man asleep in a bed.

Is Iceland the best football team in the world per capita? England suffered a 2-1 defeat to Iceland in the European Football Championship in France. This was embarrassing for England when you consider its population is 163 times bigger than Iceland’s. We take a look at whether Iceland is now the best performing football team in the world if you compare UEFA ranking to the size of each country’s population. Plus, we take a look at the chances of a young man in Iceland and in England getting to represent their country on the pitch. Old versus young Brexit voters Many media outlets have reported that it was predominantly the older generations in the UK who voted to ‘Leave’ the EU in a recent referendum, while those under 25 were keenest to ‘Remain’. It has prompted many listeners to ask whether a referendum on this topic might yield a different result if held in a few years’ time as the electorate changes. We attempt some back of the envelope calculations with Tom Chivers from Buzzfeed. But actually – how good i

Following a referendum, the UK has voted to leave the European Union. Tim Harford and the team explore what that might mean for the UK’s economy. Most notably - what might be the impact on trade?

How are companies using our personal data? It’s a familiar concern. Online retailers are tracking us so they can sell things to us. Bricks and mortar retailers have loyalty card schemes. Our banks and credit card companies know all about us. And of course, the big computer and telecoms companies could potentially track our internet searches, our phone calls – even our location as we wander around. But this isn’t the first time that large corporations have gathered sensitive data about their customers. We tell the shadowy story of how the personal details of Americans were pooled among insurance companies more than a hundred years ago.

What is the average length of stay in a refugee camp? It is regularly reported that it is 17 years but is this true? Floppy Disks This week’s shocking revelation of the computer world was that the Department of Defence still uses 1970s floppy disks to coordinate its nuclear weapons systems. But can it possibly be true that you could fit more than three million of them on a single ten dollar USB drive? Producer: Laura Gray Presenter: Ruth Alexander
