Hello, I am doing a study on schizophrenia and cannabis use. I currently have a group of 35 schizophrenia patients who have a history of cannabis use and need to recruit a matched healthy normal control group for comparison.
I was wondering if u had any information on drawing a matched control group using z-scores? And how one can calculate this easier on spss rather than by hand? Although I'm willing to do this by hand if needed. I must create a matched control group on the variables: age, gender, IQ, years of education and cannabis use. I'm terrible at stats!
