This video is part of a short (90 minutes) course titled "Statistics literacy for non-statisticians".

I hope you enjoy this course on statistics literacy. The course is mostly focused on terminology and concepts. There's no math or coding!

If you want to dive deeper into the wonderful world of statistics using a rigorous but hands-on approach, consider taking my full-length Udemy course or reading my textbook.
