I am hoping to test an interaction effect, though being new to statistics/quant research in general, I am a little unsure as to which test would be most appropriate.
I have read around using regression and a two-way ANOVA to test interaction, but I feel as if they may not work with my variables.
My IV variable is nominal with 5 categories My moderating variable is ordinal with either two or three groups (undecided whether I do high/low or high/medium/low) Whilst my DV is a scale variable
Any help regarding what statistical test would be most appropriate would be greatly appreciated! Also, if you know of any suggested reading in the area, do please let me know.
