JASP Statistics

We are proud of this book. Note the 30% discount for community members!

A new blog post! (this is one of the last JASP announcements on X, since we are switching completely to Bluesky)

Just out: JASP 0.19.2!

Predictive analytics for quality control in JASP!

RT @mzloteanu: #statstab #232 Bayesian Interval-Null Testing Thoughts: @JASPStats has a module for Equivalence Tests that include Bayesian Overlapping and Non-Overlapping Hypothesis Testing. #equivalencetests #bayesfactors #jasp #noeffect #bayes

RT @BartosFra: We are in the final phases of preparing a new update of @JASPStats. I'm creating examples for the completely revamped Meta-Analysis module - check out how stunning forest and funnel plots can be created with only a couple of mouse clicks! #metaanalysis

JASP is now on Bluesky!

RT @BobMuenchen: Updated reviews of the many wonderful GUIs for #Rstats! @BlueSky_Stat @jamovistats @JASPStats @efprime #AnalyticFlow #statistics #datascience #machinelearning #BigData #Analytics #AI #biostatistics @MedicalResearch @medresearchnews @SixSigmaDaily

Discovering Statistics Using JASP! @ProfAndyField

RT @mzloteanu: Completely missed the release of this "Robust Bayesian t-test" module by @MaxMa1er in @JASPStats. It uses Bayesian Model Averaging (8 models; equal/unequal var + normal/robust tests) to quantify relative evidence (BFs). Nice mini #multiverse analysis.

JASP 0.19 has extensive functionality for making raincloud plots! Will they replace the bar plot and line plot in statistical reporting?

Out now: JASP 0.19!

RT @Skyliuww: Pleasure to be invited by the PG Skill Workshop @PsychCardiffUni to share the amazing #JASP with my peers. Special thanks to @EJWagenmakers and Michael for their amazing @JASPStats workshops. Thrilled to see the positive feedback and engagement from everyone involved!

A final reminder as the workshop season draws near. Two workshops in Amsterdam (with Richard Morey and Michael Lee)

Mark Goss-Sampson has updated his free JASP user guide!

Workshops in Amsterdam!

Bayesian State Space models in JASP! A blog post by Fridtjof Petersen.

Over 310 professors and students across 69 countries have let us know that JASP is used to teach courses at their university. Is your university missing from the map? Please let us know at communications@jasp-stats.org!

RT @Sophie_McBridee: Extremely happy to end Thursday on such a high note 🎉 New open access article with @aitorgarces1 on the use of @JASPStats as a data analysis tool in Second Language Research. Find the article in @TEISEL2022 by following this link:
