Three months ago we finished Why R? 2020 conference. The highlights of the conference were Discussion Panels! Today we would like to remind you about the Statistical Misconceptions panel. The video from the recording is at the end of the post.

During this Discussion Panel Frank Harrell, Olga Vitek, Małgorzata Bogdan and Jarek Harezlak shed some light on common statistical mistakes.
