Question

Prepare a report using Excel as your processing tool to process 3 simple regression analyses.
1. First run a regression analysis using the Incarceration Services column of all data points in the AIU data set
from Unit 1 as the independent variable and the Legal Services satisfaction column of all data points in the
AIU data set as the dependent variable.
2. Run a second regression analysis using the Incarceration Services column of all data points in the AIU data
set as the independent variable and the Sentence satisfaction column of all data points in the AIU data set
as the dependent variable.
3. Run a third regression analysis using the Incarceration Services column of all data points in the AIU data set
as the independent variable and the Criminal Justice satisfaction column of all data points in the AIU data
set as the dependent variable.
4. Create a graph with the trend line displayed for each of the 3 different regressions. What are the least
squares regression-line equations for each of the 3 different regressions? What are the slopes and the y-
intercepts? What are the R-squared values for the 3 different regressions? Finally, make very specific
comments and give reasons regarding any similarities or differences in the output results. Which regression
produces the strongest correlation coefficient result? Why?
Assignment Guidelines
 Following the steps listed in the assignment description, run 3 separate regression analyses.
 Create a graph for each of the 3 regression analyses.
 Answer the following questions for each graph:
o What are the slopes?
o What are the y-intercepts?
o What are the R-squared values?
 Analyze the 3 graphs, and write 1–2 paragraphs regarding the correlation strength for each one.
 State which graph you believe produces the strongest correlation coefficient result. Explain your answer.
 Copy and past your graphs into a Word document, and insert your...
