SPSS HOMEWORK 4 40 POINTS Problem Set 1: The Two-Factor ANOVA for Independent Measures Research Scenario: A clinical psychologist is interested in whether a new training program will impact the severity of trauma symptoms in first responders. He is also interested in whether different types of first responders experience different levels of trauma, and whether there is a difference in how the treatment programs help these responders. To help answer this question, he recruits paramedics, firefighters, and police officers who are entering their first year of service. He divides each group in half. one half receives the original training program, and the other half receives the new training program. After their first year in service, the psychologist administers the Davidson Trauma Scale (DTS: Davidson, 1997). The DTS is a self-report instrument that indicates the presence and severity of trauma symptoms. It is often used to detect PTSD, with scores ranging from 0 to 136, and a mean in the general population of 11 (Davidson, Tharwani and Connor, 2002). The results for all groups are in the table below. Due to unequal samples, some groups had more participants than others. Conduct a two-way ANOVA to determine the effect of training program and type of first responder on DTS scores. Create a multiple line graph that shows the difference in DTS scores among the groups.
