An appreciative comment on YouTube reminds me I haven’t mentioned Significance Roulette for a while, yet its message that a p value can’t be trusted remains as relevant as ever. Dance of the p Values The dance of the p …
Reminder: Significance Roulette Still Tells Us a p Value Can’t be Trusted Read more »
A recent viewpoint article (free download) in JAMA argues that decisions should not be based on mere p value criteria, but need “consideration of the outcome in terms of effect size and accompanying CIs, [and] placing the findings from the …

In brief: Curves picture how likelihood varies across and beyond a CI. Which is better: One curve (plausibility picture) or two (cat’s eye)? Which should we use in ITNS2? Curves can discourage dichotomous decision making based on a belief that …
