R demo | Paired Samples t-Test | How to conduct, visualise and interpret

In this video, we'll learn how to produce this statistically rich plot you see on the thumbnail using only one simple command, how to interpret all the results and see what happens if we use a wrong test.

If you only want the code (or want to support me), consider join the channel (join button below any of the videos), because I provide the code upon members requests.

Enjoy! 🥳

I used this and I can not find an option to swap graph position. So the after and before are presented in a opposite fashion e.g before - after, rather than after - before. Thanks!
