2. A child psychologist wants to find out if playing video games with violent content makes kids
more prone to violent behavior. The psychologist has children come into a lab and has a

of children play a game with no violence (control group). Then the psychologist watches the
kids play with other children and records any violent behaviour.
1. How could this be done as an observational study? Be specific about how you might
