Setting up the Study Hypothesis

In this study, we are asking whether there is an interaction between the difficulty level of the exam and the time of day of testing for students who are taking the exam at a "different" time (other than during the regularly scheduled class period). Our emphasis is on the interaction between the two variables, but we may also want to test the main effects for difficulty level and time of day.

 

Now that we have set up our hypothesis/hypotheses, we can proceed to our calculations.
