i think that this is the best explanation avaliable on youtube. i was so confused about when you do post hoc because everyone talks about significant interaction and not sig mean eff. THANK U
Quick question at 9:06. You say that there are 8 means, which means that the are 24 potential pairwise comparisons. Isnt this incorrect? Shouldnt there be 7+6+5+4+3+2+1 = 28 comparisons?
Thank you so much, so....... if I only have a factor with 2 options ( black or white ) , the pos hoc test it's not recommended cuz the answer it's visible, differences may be in group 1 vs group 2 ( no margins or other factor levels might be involved?) thank u so much
Thanks for the video. I read that when the interaction is significant we cannot interpret the F ratio results of the factors individually ... this means we cannot carry on POST HOC ANALYSIS...? your videos says another thing Can you help me understand better?
Thank you. These were made to help a class I taught from 2014 to 2016. I know they're pretty dull, but I just needed some material to help the students understand the textbook and lectures. Glad they helped someone else understand :)

I had to re-teach myself all of this for my master's, Christ. Thank you, this was helpful.
Thank you! This lecture is really helpful. Couldn't find this explanation basically anywhere else on the internet after a 2-hour search.
I second this comment. Gonna explore more if your channel
