Problem Set 2: Linear Regression Analysis

Research Scenario: A social psychologist isinterested in whether the number of days spent in a refugee camppredicts trauma levels in recently resettled refugees. Heinterviews 17 refugees to determine how many days they spent in arefugee camp before being resettled, then administers the HarvardTrauma Questionnaire Part IV (HTQ Part 4), where a higher scoreindicates higher levels of trauma (Mollica et al., 1992). Hecompiles the information in the table below.
