Using the SPSS software, open the Afrobarometer dataset or the High School Longitudinal Study dataset (whichever you choose) found in the Learning Resources for this week. Based on the dataset you chose, construct a research question that can be answered with a multiple regression analysis. Once you perform your multiple regression analysis, review Chapter 11 of the Wagner text to understand how to copy and paste your output into your Word document. Write a 1- to 2-page analysis of your multiple regression 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. Part 2 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. 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.

Part 1. Frankfort-Nachmias and Leon-Guerrero (2018) noted that the precision of a confidence interval can be enhanced by increasing the sample size. Write a 250- to 300-word response to the following: How does sample size affect the validity of a study? What factors determine the size of an ideal sample? How is the sample size calculated? Reference: Frankfort-Nachmias, C., & Leon-Guerrero, A. (2018). Social statistics for a diverse society (8th ed.). Thousand Oaks, CA: SAGE Publications, Inc. Part 2 Respond in 150 words or more Sometimes students will choose a population that is so large the sample would also be large. I call it looking at an entire forest instead of looking at a single tree. What do you think a researcher could do to decrease the population size? PART 3 Write a 250- to 300-word response to the following: Select one of the sampling designs introduced in this week’s readings. Give a brief introduction of the sampling design, and explain where you might apply it most successfully. PART 4 Respond in 150 words or more I agree that probability sampling is a good way to go. Can you think of research or a project it would work in?
