No industry is perfect. But the imbalance is hard to miss. One sector must prove its products are safe & effective. The other profits by avoiding that responsibility. If we care about transparency and accountability, scrutiny shouldn’t be one-sided. (Source: For The Greater Glory of Science) #EpiSky

Yes, ChatGPT can help you write #rstats code, but so can this old Wiki I created with example code used for common data wrangling needs. Who knows, you might find some gems in there.🤷‍♀️

1. Ran Tian: Statistical Practice in Sport and Exercise Science: A Meta-Research Study.
We studied 146 studies. Most used multilevel models or t-tests/correlations/ANOVA. In 27% the wrong methods were used (statistical test did not match data structure). Collaborate with a statistician!

I recently discovered Conventional Comments (conventionalcomments.org) for providing a pseudo-standard set of labels for feedback and just tried it for an article review and it was really helpful to specify issues vs. thoughts vs. suggestions, etc. Hopefully it's helpful for the authors too!
We strongly suggest using the following labels: praise: Praises highlight something positive. Try to leave at least one of these comments per review. Do not leave false praise (which can actually be damaging). Do look for something to sincerely praise. nitpick: Nitpicks are trivial preference-based requests. These should be non-blocking by nature. suggestion: Suggestions propose improvements to the current subject. It’s important to be explicit and clear on what is being suggested and why it is an improvement. Consider using patches and the blocking or non-blocking decorations to further communicate your intent. issue: Issues highlight specific problems with the subject under review. These problems can be user-facing or behind the scenes. It is strongly recommended to pair this comment with a suggestion. If you are not sure if a problem exists or not, consider leaving a question. todo: TODO’s are small, trivial, but necessary changes. Distinguishing todo comments from issues: or suggestions: helps direct the reader’s attention to comments requiring more involvement. question: Questions are appropriate if you have a potential concern but are not quite sure if it’s relevant or not. Asking the author for clarification or investigation can lead to a quick resolution. thought: Thoughts represent an idea that popped up from reviewing. These comments are non-blocking by nature, but they are extremely valuable and can lead to more focused initiatives and mentoring opportunities. chore: Chores are simple tasks that must be done before the subject can be “officially” accepted. Usually, these comments reference some common process. Try to leave a link to the process description so that the reader knows how to resolve the chore. note: Notes are always non-blocking and simply highlight something the reader should take note of.

New paper finds that selective reporting remains the most replicable finding in science: journals.sagepub.com/doi/full/10.... I especially like their new exploratory metric 'p-values per participant'. Some papers had 11 p-values per participant! 🤯

There still seems to be a lot of confusion about significance testing in psych. No, p-values *don’t* become useless at large N. This flawed point also used to be framed as "too much power". But power isn't the problem – it's 1) unbalanced error rates and 2) the (lack of a) SESOI. 1/ >
aaronjfisher.bsky.social Aaron Fisher @aaronjfisher.bsky.social · 23d
But here's, the thing, p values and significance become useless at such large sample sizes. When you're dividing the coefficient by the SE and the sample size is in the tens of thousands, EVERYTHING IS SIGNIFICANT. All you're testing is whether the coefficient is different than zero.

I'm excited to share a new version of the Air formatter for #rstats, with support for tabular formatting! Super useful with `tibble::tribble()` calls or `data.table::fcase()`.

It's currently experimental as we're looking to get feedback on the feature, so please let us know what you think.

How FAIR is shared data in psychology?

We analyzed 11,384 datasets (2013–2024): They're findable, but less reusable!

What relates most to differences in FAIRness? #Repository choice.

FAIRness differed mainly by repository, with GitHub and OSF showing lower median scores than PsychArchives, Zenodo, and Figshare
