The "More or Less Behind the Stats" podcast episode, aired on January 24, 2024, titled "Shopping, Shipping and Wind Chill-ing," hosted by Tim Harford, explores various statistical topics ranging from the accuracy of certain claims to the impacts of shipping disruptions and the science behind wind chill.
The episode begins by examining a claim made by Labour's Shadow Chancellor, Rachel Reeves, regarding the increase in the average weekly shop cost in the UK. According to her statement, this cost has risen by £110 since the last general election. BBC's head of statistics, Robert Cuff, clarifies that this figure is derived from a 20% increase in prices over four years according to the Consumer Prices Index. However, upon further analysis, they conclude that the claim only makes sense if one assumes an average weekly shop of about £500, which is not accurate. The actual average spending on food and drink is closer to £75. The £110 increase actually relates to total weekly spending, not just the weekly shop.
The podcast then shifts to the impact of recent attacks by Houthi rebels in Yemen on international shipping. The attacks have forced many ships to reroute around the Cape of Good Hope instead of passing through the Suez Canal. The additional fuel cost per container ship for this detour is around £1 million. Peter Sand, Chief Analyst at Sunita, an ocean and air freight analytics platform, explains that while this is a significant cost, the larger financial impact comes from the need to deploy additional ships to maintain service levels due to the longer journey. Shipping rates have consequently surged by more than 200% in a span of five weeks.
Next, the episode explores the claim of 32.6 million GP appointments in England in September 2023. After investigation, it is clarified that these figures refer to appointments at general practices, not specifically with GPs. About half of these appointments are conducted by GPs, and around 10% are missed. The number of appointments in general practice far exceeds those in hospitals and other parts of the NHS. The episode also notes that a small group of people, particularly those with chronic conditions, account for a significant portion of these appointments.
In another segment, the episode addresses a polling prediction published in The Telegraph, conducted by UGov, which suggested a catastrophic result for the Conservatives in a hypothetical general election. UGov's Director of Political Analytics, Patrick English, explains that their poll predicted a 120-seat majority for Labour. However, The Telegraph made an additional analysis, not endorsed by UGov, suggesting that Reform UK votes could significantly impact the Conservative Party's performance. UGov clarified that only about a third of Reform UK voters might return to the Conservatives, debunking the Telegraph's analysis.
Finally, the podcast examines wind chill, also known as the "feels like" temperature. Meteorologist Aidan McGivin from the Met Office explains how wind chill is determined by the rate of heat loss from the skin in different wind speeds. An experiment involving individuals in a wind tunnel measured heat loss corresponding to various wind speeds. Wind chill is particularly important in colder countries where it can significantly affect the risk of frostbite.
Overall, the episode provides a detailed analysis of various claims and phenomena, debunking misconceptions and providing insights into the real implications behind the statistics discussed.
