I am in urgent need of help analyzing my data for my master's thesis which is due in two days.
I did an experiment where I showed 30 participants 6 ads (originally 3 ads with 2 versions) , I am trying to prove that strength of ethnic identity (0 weak, 1 strong) and advertisement type (1 moroccan, 2 caucasian) influence the dependent variables, attitude towards the ad, attitude towards the model, and targetedness.
I have designed my research in a way where I test each dependent variable by a univariate analysis of variance with the independent variables strength of ethnic identity and ad type, but I always get an error message saying there are no valid cases.
Please if you can help I will be forever grateful.
