Scenario: 1 continuous DV = problem solving ability 1 categorical IV = exposure, no exposure 1 categorical covariate = previous preference (like, dislike, neutral)
How do I dummy code the covariate in spss? I don't want to perform a regression and/or use the covariate as a factor.
Is the following dummy coding correct? DummyLike: like = 1, dislike = 0, neutral = 0 DummyDislike: like = 0, dislike = 1, neutral = 0 DummyNeutral: like = 0, dislike = 0, neutral = 1
Do I then enter 3 covariates (vs. the original covariate/previous preference, into the covariate box when I run the analysis in spss?
Thank you.
