1) Find one research article that uses either qualitative or quantitative research methods. I would recommend searching on either the university library under the PsycInfo database or use Google Scholar. You can try searching for a topic you are interested in (police, use of force, violence, gangs, sex offenders, substance abuse, juvenile offending, etc.) and I would also include either quantitative, qualitative, or mixed methods, in your search keywords with your other keywords and hopefully something should come up pretty quickly for you.
