Thank you so much for sharing your knowledge, really appreciated it!!

Thank you so much for this video. Really so helpful to the current analysis I'm conducting. I was wondering, if I use centred scores and wanted to plot the simple slope, would the excel input be the same as the z score input ie. adding '1' and '-1' values. Furthermore, if there are other control variables within the regression equation (ie. Y = a + b1(x) + b2(z) + b3(xz) + b4(e) + b5(g)), would I include b4 and b5 in the simple slope analysis and would I include these in the excel spreadsheet for plotting the graph. Many thanks in advance.

Hey there pal, I've performed a moderated linear regression and neither of the main effects are significant, but there is a signficant interaction effect. I'm not sure how to interpret this result or what the significance of it could be. Do you have any insight?

like your video. Why is the degree of freedom got double? Is that correct, or is it because you are comparing two slopes?
