Briefly

By
  • The WHO has released new estimates of Covid mortality.  Here’s Jon Wakefield, a statistician at the University of Washington, talking about them on PBS Newshour, Radio New Zealand, BBC’s More or Less, and Checks and Balance, at The Wire in India
  • A nice new Australian electoral map, just in time for the election
  • Some interesting sound-based data display from NASA. I’m not sure how well it works as communication
  • The making of a data visualisation — all the plots that Georgios Karamanis made in the process of looking at some data and making a final graphic
  • Media Council ruling on a terrible graph accompanying a column by Shane Reti in the Northern Advocate: “Opinion pieces must be based on a foundation of fact, and should not contain clear errors of fact.  There is no doubt that the graphs presented by Dr Reti as justifying his headline and comment in his column were misleading in that they did not fairly show the trend in cases through the period.”
  • The sources of data for online panel surveys are more complicated and messy than many people expect: “We began wondering about survey data sourcing when we noticed that since 2018, the Cooperative Election Study  has included data from Dynata, Critical Mix, and Prodege. This was a shock to us because among academic researchers, the Cooperative Election Study is widely understood as a survey conducted by YouGov“
  • A Twitter thread about Tesco Clubcard, perhaps the first store loyalty programme to focus on data collection
