We all have a small number of people who heavily influence us. One of the big influences on my statistical thinking was Ray Thomas. I met him when we volunteered on several RSS committees. Sadly he died earlier this year. Links to some obituaries are below but his PhD thesis from 1999 is worth a read. The language and terms might be dated but “Statistics as facts about society” deals with many of the issues that plague us today. Continue reading Ray Thomas
There was wonderful example of a “statistics meets news” car crash on the radio this morning. Take an interviewer who seems to be uncomfortable with numbers, poorly prepared by the editors/researchers, some statistics that were not published, presented by a lobby group that has not heard of open data or modern publishing standards, and you end up with an amusing but fundamentally totally groundless piece. People deserve better. The story about the demise of the bearded collie was classic #fakenews and was of little consequence but when the same standards of data spinning and innumeracy are applied to something important we all suffer. Continue reading Not the dog’s b*ll*cks!
What’s wrong with Simon, the name that is? It’s a good name. I’ve enjoyed having it. But it is seriously out of fashion and has been for a while. Prompted by the weird experience of finding myself sitting next to a much younger one at an event earlier this week, I was keen to see just how unpopular we have become. The answer is very unpopular. Continue reading The end of Simon
The monthly release of the inflation figures (due tomorrow Wednesday 16th) is always a reminder of the futile attempts by ONS/UKSA to suppress the RPI. The RPI is the most popular statistic produced by the ONS (as measured by web hits, calls to ONS etc.) yet there’s no commentary on the RPI and the numbers do not appear in the 11 page press release. The breakdown of the RPI is hidden away in the back three pages of the 19 page data pack (just after the table that gives the rates for Lithuania, Slovakia and other EU states that the ONS presumably thinks are more interesting to users). To note the madness of this continuing practice, please find below a fairytale. Continue reading The king and his fish: the RPI fairytale
I spoke at an event about the Retail Prices Index (RPI) last week and made three points – that there is a misunderstanding about the formula effect, ONS is too influenced by economists’ ‘group think’ and weaknesses in governance. These can all be resolved easily, returning RPI to full use, if ONS and UKSA wants to. It was widely agreed that “the mess” had to be sorted out, and as the RPI cannot be killed off some modest changes to it are required. Continue reading The truth about the RPI – some brief comments
This is about a bad trend in some questionable data: the official data says that the UK has a huge balance of trade deficit in goods, it’s getting worse and the driving force behind the trend has been the growing deficit with the EU. True? Probably. This trade deterioration needs to be noted, diagnosed, discussed as part of the Brexit negotiations and reversed. Continue reading The UK’s trade deficit in goods
Can the Retail Prices Index be killed off? Should it be killed off and, if so, for what reason? Or is reform needed? A meeting is coming up (at the RSS in London, on 13 June, book here) to discuss the future of the RPI and the changes needed to all consumer price measures to keep them fit for purpose. Why not come and hear the views of John Pullinger, the UK’s National Statistician, and other experts?
Without wanting to engage in BBC bashing it must be said that this morning’s BBC Radio 4 Today programme had too many examples of sloppy use of data. There were school boy errors: focusing on the latest figure not the trend, comparing annual data to quarterly data, getting the number wrong, ignoring the impact of inflation when comparing figures over time, choosing the wrong denominator and flooding the debate with large but ultimately meaningless numbers. I am not a regular listener to the BBC’s flagship news programs but I hope they are generally better than this! Continue reading BBC and sloppy numbers
The gender pay gap is a sensitive, highly topical subject and the deadline is approaching for companies to report their data, often for the first time. It’s a shame then that the BBC article from their “data journalists” setting out to explain what’s happening, “Gender pay gap deadline: What to know“, misses some simple points and does little to help anyone who might be confused. The data is not complicated but there are various aggregate statistics in the public domain which are based on different definitions, and thus need to be used carefully and described clearly. Continue reading The BBC’s unhelpful article on the gender pay gap
The ONS published this week a new – I’d say conceptually more sound – experimental house price index. It is based on the stock of homes not the flow so tells us what’s happening to the whole market not the price of what’s just been sold. The estimate of the average price is lower than under the old methodology – £194,000 compared to £215,000 in the old measure, about 10% lower. The stroke of the methodologist’s pen has made homes more affordable even though no prices have changed! Perhaps this is the time to reflect on the full range of house price estimates at our disposal – and, dare I say it, how meaningless the average numbers are? Depending on what you count and how you add the numbers up, the resulting averages can be wildly different, as much as £100,000 apart. Continue reading The price of a house – a stupid average
