Consider the Marks data set, where the goal is to predict the final exam mark. Possible explanatory variables are the marks on Assignments 1 and 2, Tests 1 and 2, and Quiz marks. The tests and the final exam are written in a classroom, with all computations done manually with a calculator. The quizzes are done with online testing software, and the calculations can be done manually with a calculator or with Excel. Students can attempt the quizzes as many times as they wish before the due date (the quizzes are similar but not the same).The assignments are Excel-based and include a written report on the Excel analysis. Based on this information, which of the evaluations do you think would be the best predictor of the final exam mark, and why?
