Oct 25, 2019 at 11:45 comment added carlo I don't understand the "six times a single regression line" part. what of the two plots are you talking about?
Oct 25, 2019 at 11:41 comment added Sextus Empiricus @Carlo the reason that I started to think about the interaction term is because of the title "regression with multiple independent variables vs multiple regressions with one independent variable" which I associated with making multiple regression lines. That's what I did in the code it is actually six times a single regression line. The effort has gone too far too change it back now, but I will add an extra clarification.

Oct 25, 2019 at 11:40 comment added carlo I just saw your last edit. way better, I would put the first part in the end and avoid to compare multiple regression with interaction with simple regressions (use multiple regression w/out interaction instead). I'm deleting my first comment.
Oct 25, 2019 at 11:37 comment added carlo that's better. but it work's because the two predictors are independent. it wouldn't work otherwise, and correlation between covariates are the main reason to use multiple regression in the first place. actually, I think that's not a good idea to introduce interaction to someone who still doesn't understand difference between simple and multiple regression

Oct 25, 2019 at 11:32 comment added Sextus Empiricus @carlo I have changed it accordingly by splitting up the question and making the first part more explicitly about the interaction term.
