Health Nerd added,
Have another gander at those numbers The means are a ~tiny~ bit different, but the quartiles are virtually identical! The medians are exactly the same
And the test that the p-value comes from is actually a Wilcoxon signed-rank test, which compares DISTRIBUTIONS, not mean values In other words, it's VERY unlikely you'd see two samples with the same medians, virtually identical quartiles, but a p of 0.022pic.twitter.com/bTLVXJ6CsF
So it's not just me then. This warrants an entry on PubPeer I think, if not an outright letter to the editor.
Nahhh I think @sTeamTraen solved the mystery. It's paired data, so the summary stats don't actually tell you much. With enough finagling I think the distribution is ~possible~, just really really weird
One weird thing - the ~mean~ score of participants on the STAI was 45-50. A score above 40 is considered symptomatic for anxiety disorders
Also, just noticed that this is clearly an error. Can't have an UQ of 49.8, the results are all integers so it should be 49.0 or 49.5pic.twitter.com/wvQkYFz9ko
