Question

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)
