• A social psychologist is interested in whether the number of days spent in a refugee camp predicts trauma levels in recently resettled refugees. He interviews 17 refugees to determine how many days they spent in a refugee camp before being resettled, then administers the Harvard Trauma Questionnaire Part IV (HTQ Part 4), where a higher score indicates higher levels of trauma (Mollica et al., 1992). He compiles the information in the table below.Conduct a bivariate linear regression to analyze the research question.

The steps will be the same as the ones you have been practicing in Part 1 of the assignment?the only difference is that you are now responsible for creating the data file as well. Remember to name and define your variables under the ?Variable View,? then return to the ?Data View? to enter the data.

 Days Spent in Refugee Camp HTQ Part 4 Score 12 0.4 73 1.1 60 0.9 105 2.3 98 1.7 76 0.3 89 0.7 173 2.6 189 3.1 203 3.0 138 1.9 215 2.5 71 0.7 67 1.2 63 1.8 184 2.9 63 0.6
• 1.Paste SPSS output
• 2.Construct a scatterplot of the relationship between the 2 variables. Plot the regression line on this graph.
• 3.Are the number of days spent in a refugee camp predictive of trauma in this sample? Write a Results section in current APA style describing the outcome. All homework ?Results sections? must follow the example given in the SPSS tutorial presentation and the Course Content document ?Writing Results of Statistical Tests in Current APA Format.?The statistical statement for a bivariate linear regression must include at least the equation of the line and the confidence interval for the slope (the second row under Confidence Intervals in the output), as well as a decision about the null hypothesis.
