This page is continuously updated with everything you need for the course: the lecture slides and handouts, interactive applets, the JASP datasets and result files, and extra written explanations. Use the toggle in the sidebar to switch between light and dark mode.

Slides

The handouts are 1 continuous page, while the slides are spread across multiple pages (navigate with the arrow keys). To get a pdf, I recommend you use the print option in your browser to print the handout to pdf (open the handout and press ctrl + p (Windows) or cmd + p (MacOS)). The chapters page lists the topics of each recording with their start times, so you can skip to the part you need. It is based on the lecture transcript, and the sentences under each chapter come directly from there.
