Multi-factor ANOVA and Interactions

One of the powerful features of ANOVA is its ability to test multiple hypotheses at the same time, including tests of interactions between effects. To learn more, visit www.statstree.org

I really like this exposition. too many of these vids are just assinine walk thrus of MS calcs with no intuition on what its actually trying to accomplish. thanks for making this.

This is very helpful explanation, explaining three chapters 1) One wanova, 2) Two way anova and 3) Multi-factor anova. I hope you make some calculation which can be done using R output, like average difference using Emmeans. Thank you alot.

Lots of information about use cases of Multi-Factor ANOVA but sadly nothing on the logic and methodology behind it. While I understand one-factor ANOVA and that it's based on deriving the population mean from sampling distribution of the sample mean, I still don't understand don't how the interactions are estimated, although I feel the principle is close to one-factor ANOVA.

I am really lost I want to test the effect of four accents on accuracy and response time is it two-way anova? or multi-factor anova?

Love the way you explained interactions at 23:15.
