Question 2

I am interested in whether students are more attentive in early morning classes or late morning classes. I use two classes with identical subject matter and the same instructor but one is taught at 8:05 AM and the other is taught at 11:20 AM. I videotape the class and have three judges rate the attentiveness of the students. In this experiment the independent variable is

A) the time of the class.
B) the age of the students.
C) the attentiveness ratings.
D) the subject matter of the class.
