Tim Harford investigates some of the numbers in the news. This week:(00:32) A government minister has informed the nation that average teacher pay in England is around £54,000. Radio 4 listeners are howling at the radio in disbelief. Surely someone from the IFS would be able to explain all this? We interview someone from the IFS to explain all this.(06:32) A headline in the Independent suggests that Russian soldiers survive an average of 20 minutes when they get to the front line, citing a historian, citing Russian bloggers. Is the number a good one? We take a peek into the murky information ecosystem that surrounds the war in Ukraine.(15:00) A loyal listener has resent a burning question that - mortifyingly - he first asked us nearly three years ago: why is air travel cheaper than rail travel? We push our guilt deep, deep down then make it worse by challenging the premise of the question. (21:18) Is every shuffle of a deck of cards an unprecedented event in the history of the universe? It’s a bold claim, but maths YouTuber and comedian Matt Parker has done his homework. We invite him into the studio to make his case - and show off his shuffling skills.More or Less is the programme that looks at numbers and statistics in news and in life.
