The independent variable is:  TV on  /  TV off .  It can only be changed by the
psychologist who is running the experiment.

If there was a dependent variable, then it was the students' comprehension of the material they studied.  The purpose of the experiment was to determine whether It actually depended on the independent variable or not.  ( I'll bet it did. )
