We often use 7-point ratings to measure people's preferences and attitudes (e.g., “how much do you like X?” 1=not at all, 7=very much). In a new paper (just accepted at @APA's Decision; full paper at the end of thread), I demonstrate a problem with such rating measures. (1/n)

My newest paper (with David Wagner, @KiraSchabram, and @DorianBoncoeur), about human sustainability. I think this is the most important paper I have ever been a part of. https://t.co/s6Q0LGXA8V

[1/n] I recently offered a free Zoom "intro to R" data visualization workshop after popular demand. Specifically, I went through the use of ggplot2. All disciplines with no prior R skills were welcome. All free materials are below!🧵 @PhDVoice @AcademicChatter @OpenAcademics

Were I to ban one statistic from meta-analysis reporting, it's I^2. Why? It doesn't tell you anything more than the random-effects variance estimate* itself. In fact, as a proportion of RE to total variance, I^2 tells you less**.

* = which has its own issues
** = get off my lawn

I am running my three-day meta-analysis course this year, November 2-4. The course provides a thorough introduction to meta-analysis and (surprise!) the use of the metafor package for conducting the analyses in R. Further details can be found here: https://t.co/mN6sBuJj3W

Every Thursday, from 5pm (CET/CEST) until 8pm (approx), I run the 'Open Online R Stream', an open live stream where I teach R, some stats, and play some smooth jazz. More info (the schedule, topics, general format) can be found on my website: https://t.co/2Qudur2Rdh

August reminder for meta-analysis folk:

I-squared estimates between-study heterogeneity❌

I-squared is a test for between-study heterogeneity❌

I-squared > 50% means large heterogeneity❌

I-squared measures proportion of total variability due to between-study heterogeneity✅

A 🧵 on burnout

Yesterday I learned that when people are burnt out, their amygdala enlarges. For all you non-neuroscientists, here's what that means and why it's important. 1/
