Theory and Practice of Bayesian Hypothesis Testing: An Online JASP Workshop

Reverend pulling a bunny from a hat

Our annual JASP workshop takes place on August 26–27 and there are still places available. Due to the COVID-19 pandemic, this year’s workshop will again take place online and the fees will be lower than usual. We aim to make use of a number of tools to create a smooth, fun, and interactive learning experience. Below is a summary of the program—more information on the program and fees can be found on our workshop website.


In this two-day workshop, plenary lectures provide the theoretical background of Bayesian statistics and Bayesian hypothesis testing; in addition, practical exercises demonstrate how the JASP program is applied to a wide range of common statistical scenarios. This workshop provides an appreciation for the theoretical foundations that underlie Bayesian hypothesis testing, but its main goal is to teach participants the practical skills needed in order to execute and report Bayesian analyses for the models that form the bread-and-butter of statistical inference: t-tests, correlations, regression, ANOVA, and contingency tables. Additionally, we will discuss new features, including Bayesian model averaging for linear regression (based on Merlise Clyde’s BAS package in R) and our Bayesian A/B test.

Target audience

This workshop will provide attendees with a friendly, gentle introduction to the theory behind Bayesian hypothesis testing and is therefore suited for everyone new to Bayesian inference. The possibilities of practical Bayesian hypothesis testing using JASP will be illustrated with concrete examples. At the end of this workshop, participants should be able to carry out statistical analyses in JASP, interpret the output, and report the results. Our examples are general and the proposed methodology applies across the empirical disciplines (e.g., psychology, sociology, biology, economics, etc.).


Plenary sessions will be given by Richard D. Morey and Eric-Jan Wagenmakers.

Online “lecture hall”

We aim to make use of a number of tools to create a smooth, fun, and interactive learning experience. Lectures will be held on Zoom, and video recordings will be made available to workshop participants. Moreover, you will be invited to a Slack workspace where our team will assist you and answer any questions you might have about the materials. During the breaks you have the opportunity to socialize using

The online workshop will mainly take place during business hours in our local time zone (CEST; GMT +2 hours). However, we will attempt to accommodate the needs of international participants as well.


If you are interested in participating in the online version of the workshop, we invite you to register in our Conftool system. Registration will remain open until August 25.


More details about the workshop can be found on our workshop website.

Take care, and we hope to see you soon!
