On June 6th I gave a one-hour lecture for SIOS, the Student Initiative for Open Science in Amsterdam (you can follow them on Twitter @StudentIOS). The slides are at https://osf.io/5s9uq/, and a YouTube video of the entire lecture is at https://t.co/u7bkqaC6Ko.

                                            
                      
                      

Abstract

This presentation consists of three parts. In the first, I will present a whirlwind tour of the p-value’s many statistical peculiarities. In the second, I will list reasons for the p-value’s continued dominance across the empirical sciences. One such reason is that the p-value can be used to silence your skeptics — that is, to discredit the null hypothesis that the experimental treatment was utterly ineffective. In the third part I will demonstrate how Bayesian hypothesis testing with JASP (jasp-stats.org) can provide a practical, principled, and easy-to-use alternative.

Also included are pictures of my son Theo, the devil (these are not the same), and Adam Sandler.
