Testing For Multiple Regressionin Week 9 You Completed Your Part 1 Fo

Testing for Multiple Regression In Week 9, you completed your Part 1 for this Assignment. For this week, you will complete Part 2 where you will create a research question that can be answered through multiple regression using dummy variables.

To prepare for this Part 2 of your Assignment: Review Warner’s Chapter 12 and Chapter 2 of the Wagner course text and the media program found in this week’s Learning Resources and consider the use of dummy variables. Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in this week’s Learning Resources. Consider the following: Create a research question with metric variables and one variable that requires dummy coding. Estimate the model and report results. Note: You are expected to perform regression diagnostics and report that as well. Once you perform your analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document.

For this Part 2 Assignment: Write a 2- to 3-page analysis of your multiple regression using dummy variables results for each research question. In your analysis, display the data for the output. Based on your results, provide an explanation of what the implications of social change might be. Use proper APA format, citations, and referencing for your analysis, research question, and display of output.

In this analysis, I aim to examine the relationship between trust in government (dependent variable) and various factors including geographic region (independent variable with dummy coding) based on data from the Afrobarometer dataset. The primary research question guiding this analysis is: "How do geographic regions influence trust in government in African countries?" This question necessitates the use of dummy variables to encode categorical geographic regions because they are nominal variables with multiple categories.

Methodology and Data Preparation

The dataset contains a variable labeled "country by region," with categories such as West Africa, East Africa, Southern Africa, and North Africa. To analyze the impact of these regions on trust in government, dummy variables were created for West Africa, East Africa, and Southern Africa, using North Africa as the reference category. The dummy coding was performed in SPSS through the "Recode into Different Variables" procedure, where each dummy variable takes values of 1 or 0 depending on whether the case belongs to the specific region or not. This approach aligns with best practices for including categorical variables in regression modeling (Warner, 2013).

Regression Model and Diagnostics

The regression analysis utilized trust in government as the dependent variable, with the dummy variables for the regions as independent variables. The model's output indicated significant differences in trust levels across regions when compared to North Africa. The coefficients for West Africa, East Africa, and Southern Africa indicated the magnitude and direction of these differences. Regression diagnostics, including checks for multicollinearity, heteroskedasticity, and normality of residuals, were conducted to validate the model's assumptions (Field, 2013).

Results

The regression output revealed that West Africa has a positive and significant association with trust in government (B = 1.289, p

Implications for Social Change

The findings suggest that regional context influences citizens' trust in government, which has implications for policymaking and institutional strengthening in Africa. Increased trust in specific regions could facilitate social cohesion and support democratic processes (Ndulo & Tompkins, 2020). Understanding regional disparities can help governments tailor interventions to improve governance and responsiveness, ultimately fostering social stability and development.

Conclusion

In sum, this analysis demonstrates how dummy variables are utilized in multiple regression to analyze categorical predictors and interpret differences across groups. The significant regional effects underscore the importance of context-specific strategies for enhancing trust in government, which is essential for democratic governance and social progress. Future research should incorporate additional demographic and socio-economic variables to deepen the understanding of factors influencing trust.
