I have one categorical predictor coded as 0 or 1 for a sample of about 290. Based on some research, I want to control for 4 covariates. One is continuous (age) and the rest are categorical (gender, ever having used certain drugs as either yes or no).
My outcome is number of violent acts - this is what I'm having trouble with. According to a professor at my university this isn't a true continuous variable as it is an interval variable. This confused me as I've used interval variables as continuous in other tests.
What type of test would I use if my outcome was continuous? Do I need to use a different one for my interval data?
I am using SPSS to analyze my data. After finding base associations (using t-tests) between my predictor and outcome and covariates and outcome, I tried to go further. I did a univariate analysis of variance (under general linear models) with my predictor as a fixed factor. This seems logical as there's a section for covariates, but I honestly have no idea. Any guidance would be much appreciated.
