I’m interested in seeing whether or not online supplementary material helps students achieve higher grades in statistics. I assign 10 students into a class using an online textbook resource whereas 10 separate students are assigned into a class using just the textbook. I record their final course average (final course grade). Using the following data (testing at an alpha of .05), assess whether those that used the online resources + textbook (group 1) did better than those just using the textbook (group 2). Online resources + Textbook (group 1) Just textbook (group 2) 95 90 90 86 92 75 92 87 84 85 86 83 91 90 92 83 80 85 82 78 Independent variable: _______________________ Dependent variable: _________________________ Null (H0): ________________________________ Alternative (Ha): ________________________________
