Question
Suppose a sample of n students were given a diagnostic test before studying a particular module and then again after completing the module. We want to find out if, in general, our teaching leads to improvements in students' knowledge/skills (i.e. test scores).
Analyze the data in two different ways: in question 1, please treat the data from the Pre-Module Scores and the data from the Post-Module scores as independent data; that is, do no pair them.
For question 2, you will repeat the analysis, but with the data paired.
