I'm using a large dataset with 12 pairs of variables that I'm interested in: a value of a particular factor before and after an intervention/control. So there's 'BeforeA', 'AfterA', 'BeforeB', 'AfterB' and so on.
I need to analyse these and show them in a before/after line graph with all the lines together. I've spent over a week trying to learn how to do an ANOVA or ANCOVA analysis (possibly one-way between subjects ANOVA?), I've watched and copied several videos but it's always returned error results and I have no idea if I'm using the right approach.
What method would you suggest in SPSS and can you direct me to a video demonstrating how to do it?
Thank you so much, this is exhausting me.
