“[Of] 25 replication studies, 7 (28%) studies demonstrated robust replicability, meeting all three validation criteria: achieving statistical significance (p < 0.05) in the same direction as the original study and showing compatible effect size magnitudes as per the Z test (p > 0.05).”
New Replication Project in sport and exercise science shares it results: Out of 25 replication studies performed, 56% yielded significant results, but only 7 (28%) revealed a similar effect size. Several problems related to the quality of are discussed.

Can we all just agree to stop calling standardized mean differences "Cohen's d" in our scientific manuscripts? It's misleading, and IMHO leads to lazy reporting. If you want shorthand I'd recommend SMD (i.e., what Cochrane uses), and *always* report how the SMD was calculated #stats

Just out of curiosity, does anyone know of papers looking at the effectiveness of the bootstrap-t (studentized) CI method for standardized mean differences (e.g., Cohen's d) compared to other methods (e.g., BCa). My very brief search for papers has come up empty. #stats

Is there a list somewhere out there for open source/access teaching/learning resources for statistics? Currently trying to create a document organizing all these resources for when I start teaching next semester #stats ☺️

RAND is hiring social and behavioral scientists to fill some really exciting positions (LA, DC, PGH, Boston), and offering exceptional salary+benefits. Would highly recommend this - RAND was an extremely valuable experience early in my career.
