What would be the appropriate test for a study that has:
2 categorical independent variables with 2 levels each, 1 moderator variable (and would it matter if my moderator is categorical or continuous?), and 1 continuous dependent variable
I am still undecided on whether I will propose my variables as being correlated or as predictor/criterion variables.
If the results of my moderator (which will most likely be measured on a scale of 1 to 7) are scored as low (1-2.9), medium (3-5), and high (5.1-7), would I be correct in assuming that, as there are more than 2 'levels' of the moderator, I will have to encode them into dummy variables if I'm using SPSS?
Would my choice of carrying out multiple regression be appropriate for this study?
