# Regression Analysis: 4 Steps for Benefits and Job Satisfaction

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

First run a regression analysis using the benefits column of all data points in the data set as the independent variable and the intrinsic job satisfaction column of all data points in the AIU data set as the dependent variable. Create a graph with the trendline displayed. What is the least squares regression line equation? What are the slope and the y-intercept? What is the R-squared value?

Next, run a regression analysis using the benefits column of all data points in the data set as the independent variable and the extrinsic job satisfaction column of all data points in the AIU data set as the dependent variable. Create a graph with the trendline displayed. What is the least squares regression line equation? What are the slope and the y-intercept? What is the R-squared value?

Next, run a regression analysis using the benefits column of all data points in the data set as the independent variable and the overall job satisfaction column of all data points in the AIU data set as the dependent variable. Create a graph with the trendline displayed. What is the least squares regression line equation? What are the slope and the y-intercept? What is the R-squared value?

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?

These are the key components I am focusing on:
Run regression with Benefits and Intrinsic - provide Excel output
Run regression with Benefits and Extrinsic - provide Excel output
Run regression with Benefits and Overall - provide Excel output
Graphs with trendlines for all three regressions
Slopes and y-intercepts for all three regressions
R-squared values for all three regressions
Comment on similarities, differences and reasons
Which regression produces the strongest correlation coefficient and why?
