EU Treasury report

This week there was much debate over the Treasury report which modelled how leaving the EU would affect the economy. Tim Harford speaks to the Spectator’s Fraser Nelson about how the document was presented to the public, and how it was reported. Chris Giles of the Financial Times explains that there are useful points to take from the Treasury’s analysis.

What is the most expensive “object” ever built? The environmental charity Greenpeace has claimed it is set to be the most expensive object on Earth. But could it really cost more to build than the Great Pyramids? We take a look at some of the most costly building projects on the planet.

Chances of serving on a jury

A listener in Scotland is curious to know what the chances are of being selected for jury service. Several of his family members have received summons, but he has not. We look at who is eligible to serve, and what your odds are of receiving a summons.

European Girls Maths Olympiad

Last week we told the story of how the European Girls Maths Olympiad (EGMO) came into being. We followed the UK team on their recent journey to Romania to compete against 38 other teams from Europe and around the world.

Life expectancy of a Pope

In 2014 Pope Francis alluded to the fact he didn’t expect to live more than another two or three years. A group of statisticians have taken a look at the life expectancy of popes over the centuries and decided that he may have been rather pessimistic.

The curse of the London Olympics

In a similar vein, is there an unusually high death count among athletes who took part in the London Olympics in 2012? The French press seem to think there is. Currently news reports estimate that 18 people have so far died since taking part in the sports event. The athletes come from teams around the world and have died from all sorts of causes – from cancer to drowning, murder, suicide, a helicopter crash among other things. But is there really a link between taking part in the London Olympics and the chances of dying? Or is it to be expected, statistically speaking, that 18 people have died over the last four years?

Celebrity deaths

A number of people have asked the team if more famous people have died this year compared to other years. It’s a hard one to measure – but we have had a go at some back of the envelope calculations with data from Who’s Who and BBC obituaries. Is the intuitive feeling that more people have died this year misplaced?

‘What British Muslims really think’ poll

This week many news outlets covered polling research carried out for a documentary on Channel 4. Some of the points that came out included that half of all British Muslims think homosexuality should be illegal and that 23% want Sharia Law. But how representative are these views? We speak to Anthony Wells from the blog UK Polling Report who explains the difficulties of carrying out polling.

The number of Brits abroad

Figures released this week suggested that there was an increase in the number of people coming to the UK from other parts of Europe. But many listeners have been asking – how many Brits are living in other parts of Europe? We try to find the best figures available.

European Girls Maths Olympiad

In 2012 a new international maths competition was started at the University of Cambridge. It was a chance for female students to get a chance of meeting girls from other countries and try to solve hard maths problems, as they are under represented at most other international competitions. We hear about how the competition got started in celebration of this year's competition in Romania.

In the 1600s astronomers were coming up with measurements to help sailors read their maps with a compass. But with all the observations of the skies they were making, how do they choose the best number? We tell the story of how astronomers started to find the average from a group of numbers. By the 1800s, one Belgian astronomer began to apply this to all sorts of social and national statistics – and the ‘Average Man’ was born.

Could there really be 26,911 words of European Union regulation dedicated to the sale of cabbage? This figure is often used by those arguing there is too much bureaucracy in the EU. But we trace its origins back to 1940s America. It wasn’t true then, and it isn’t true today. So how did this cabbage myth grow and spread? And what is the real number of words relating to the sale of cabbages in the EU? Tim Harford presents.

And what is the real number of words relating to the sale of cabbages in the EU? After the recent announcement that all schools would be converted to academies, a number of listeners have asked us to look into the evidence of how they perform. Education Secretary Nicky Morgan wrote a guest post on Mumsnet and More or Less were called upon to check her numbers. The popular TV show The Only Way is Essex claimed in its 200th episode that it had contributed more than a billion pounds to the UK economy. We investigate if this is true. Plus, can we trust food surveys? Stories about which foods are good and bad for you, which foods are linked to cancer and which have beneficial qualities are always popular. But how do experts know what people are eating? Tim Harford speaks to Christie Aschwanden, FiveThirtyEight's lead writer for science, about the pitfalls of food surveys. She kept a food diary and answered nutrition surveys and found many of the questions were really hard to answer.

New alcohol guidelines were issued recently in the UK which lowered the number of units recommended for safe drinking. But are the benefits and harms of alcohol being judged correctly? We speak to Professor David Speigelhalter. Tim Harford presents. Producer: Charlotte McDonald/Richard Vadon

Mobile technology is spreading fast in Africa, and one lawyer Gerald Abila has done the maths and worked out that there are more mobile phones than lightbulbs in Uganda. We look at his figures and find that measuring them is more complicated than you might imagine. There are certainly numbers you can choose to demonstrate this, but are they the right ones? Thyroid cancer has gone up after the Fukushima accident - but it's not what you think. Japanese authorities were worried about the impact of radiation that escaped into the atmosphere after a nuclear plant was damaged during the earthquake of 2011. Around 300,000 under-19s received ultrasound scans to look for abnormalities, and the results appeared alarming. One expert claimed there were 30 times more cases than might have been expected. But a group of epidemiologists have since questioned this - they say if you survey so many people, you will always find more cases.

Stories about what foods are good and bad for you, which foods are linked to cancer and which have beneficial qualities are always popular online and in the news. But how do experts know what people are eating? Tim Harford speaks to Christie Aschwanden, FiveThirtyEight’s lead writer for science, about the pitfalls of food surveys. She kept a food diary and answered nutrition surveys and found many of the questions were really hard to answer – how could she tell all the ingredients in a restaurant curry; and how many tomatoes did she eat regularly over the past six months?
