Dr. James is a forensic psychologist interested in the relationship between mental disorders and criminality. She gets permission to study patients at both inpatient/residential mental health facilities in the state. There are over 4,000 patients currently living in these facilities. She asks patients whether they have ever been arrested for a crime and whether they have ever been convicted of a crime. She collects a sample size of 1,300. She finds that 25% (+/− 3%) report having been arrested for a crime but that only 11% (+/− 3%) have been convicted of a crime. Choose a representative sampling technique and a biased sampling technique. Explain how Dr. James would implement each of these sampling techniques.
