What is the most important driver based on regression? How do you know (e.g., are you looking at standardized or unstandardized coefficients)
What is the least important driver based on regression?
Do you have any issues with multicollinearity? How do you know? What might you do to resolve these issues (if any)?
What is the equation to predict overall satisfaction as a function of the 11 driver variables? (are you using standardized or unstandardized coefficients to describe this?)
