  • Internal Meta-Analysis: The Latest - I recently wrote in favour of internal meta-analysis, which refers to m-a that integrates evidence from two or more studies on more-or-less the same question, all coming from the same lab and perhaps reported in a single article. The post is here. This month's issue of Significance magazine carries an
  • Abandon Statistical Significance! - That's the title of a paper accepted for publication in The American Statistician. (I confess that I added the "!") The paper is here. Scroll down below to see the abstract. The paper boasts an interdisciplinary team of authors, including Andrew Gelman of blog fame. I was, of course, eager
  • Open Science DownUnder: Simine Comes to Town - A week or two ago Simine Vazire was in town. Fiona Fidler organised a great Open Science jamboree to celebrate. The program is here and a few of the sets of slides are here. Simine on the credibility revolution First up was Simine, speaking to the title THE CREDIBILITY REVOLUTION
  • Cabbage? Open Science and cardiothoracic surgery - "The best thing about being a statistician is that you get to play in everyone's backyard." --a well-known quote from John Tukey. Cabbage? That's CABG--see below. A week or so ago Lindy and I spent a very enjoyable 5 days of sun, surf, and sand at Noosa Heads in Queensland.
  • Internal Meta-Analysis: Useful or Disastrous? - A recent powerful blog post (see below) against internal meta-analysis prompts me to ask the question above. (Actually, Steve Lindsay prompted me to write this post; thanks Steve.) In ITNS we say, on p. 243: "To carry out a meta-analysis you need a minimum of two studies, and it can
  • Eating Disorders Research: Open Science and The New Statistics - I'm in Sydney, the great Manly surf beach just over the road. It's an easy ferry ride to the Opera House and city centre. Lindy and I started this trip up from Melbourne with a few days with a cousin, at her house high above Killcare beach an hour north
  • Cochrane: Matthew Page Wins the Prize! - Years ago, Matthew Page was a student in the School of Psychological Science at La Trobe University (in Melbourne), working with Fiona Fidler and me. He somehow (!) became interested in research methods and practices, especially as related to meta-analysis. He moved to Cochrane Australia, which is based at Monash
  • Draw Pictures to Improve Learning? - In ITNS we included a short section near the start describing good strategies for learning, based on empirical studies. Scattered through the book are reminders and encouragement to use the effective strategies. Now, just as we're thinking about possible improvements in a second edition, comes this review article: Fernandes, M.
  • ITNS–The Second Edition! - Routledge, our publisher, has started planning for a second edition. That's very exciting news! The only problem is that Bob and I can't think of anything that needs improving. Ha! But, seriously, we'd love to hear from you about things we should revise, update, or somehow improve. (Of course, we'd
  • Open Science DownUnder — Fiona Fidler reports - Last week, the 2018 Australasian Open Science Conference was held in Brisbane at the University of Queensland: The first conference in Oz on the themes of Open Science and how to improve how science is done. They expected 40 and 140 turned up! By all reports it was a rip-roaring
  • A Wonderful Panorama of Statistics - Bob and I have been off-air for a while, but we haven't gone away. I've been meaning for ages to blog about a wonderful book. Here it is: Sowey, E., & Petocz, P. (2017). A panorama of statistics: Perspectives, puzzles and paradoxes in statistics. Wiley. And the flyer with succinct
  • Positive Controls for Psychology – My pitch for a SIPS project - Positive controls are one of the most useful tools for ensuring interpretable and fruitful research.  Strangely, though, positive controls are rarely used in psychological research.  That's a shame, but also an opportunity--it would be an easy but substantial improvement for psychological researchers to start using regularly using positive controls.  I
  • Precision for Planning: Great New Developments - --updated with a link from Ken Kelley to access the functions in the paper, 6/28/2018-- In a new-statistics world, the best way to choose N for a study is to use precision for planning (PfP), also known as accuracy in parameter estimation (AIPE). Both our new-statistics books explain PfP and
  • Effect Sizes for Open Science - For the last 20 years or so, many journals have emphasised the reporting of effect sizes. The new statistics emphasised also the reporting of CIs on those effect sizes. Now Open Science places effect sizes, CIs, and their interpretation centre stage. Here's a recent article with interesting discussion and much
  • APS in San Fran 3: Workshop on Teaching the New Stats - Tamarah Smith and Bob presented a workshop on Teaching the New Stats to an almost sold-out crowd. I wasn't there, but by all reports it went extremely well. Such a workshop seems to me a terrific way to help interested stats teachers introduce the new stats into their own teaching.
  • APS in San Fran 2: Symposium on Teaching the New Stats - Our symposium was titled Open Science and Its Statistics: What We Need to Teach Now. The room wasn't large, but it was packed, standing room only. I thought the energy was terrific. There were four presentations, as below. Bob and Tamarah Smith have set up an OSF page on Getting
  • APS in San Fran 1: Open Science is Maturing - It was, as ever, a great pleasure to catch up with Bob last weekend. We were in San Francisco for the APS Convention. That convention has been for the last five years or so a hotbed of discussion about Open Science--many times I felt I was witnessing decisions about what
  • The Perils of MTurk, Part 1: Fuel to the Publication Bias Fire? - It's not going to be a popular opinion, but I think MTurk has become a danger to sound psychological science.  This breaks my heart.  MTurk has helped transform my career for the better.  Moreover, MTurk participants are amazing: they are primarily diligent and honest folks with a genuine interest in
  • Tony Hak 1950-2018: Champion of Better Methods, Better Statistics - It was a shock to receive the very sad news that Tony Hak died last week, unexpectedly. Too young! And only 3 years into an active retirement. Tony was an Emeritus Associate Professor, having retired in 2015 from the Department of Technology and Operations Management of RSM, the Rotterdam School
  • Badges, Badges, Badges: Open Science on the March - Here are two screen pics from today's notice about the latest issue of Psychological Science. Four of the first five articles earned all three badges, including Pre-reg! Gold! (OK, by showing just those five I'm cherry picking, but other articles also have lots of badges and, in any case, what
