Compare and contrast the use of linear and multiple regression analyses. Use concrete examples of studies from the last year, if possible.
Explain the meaning of the simple coefficient of determination in general, and explain how it might be useful to address a major issue in the news from the last year. When doing a regression
analysis, against which variables should the residuals be plotted? How would you know if the residual plots violate the regression assumptions? What information does the overall F test produce? Why
is this important?
