This experiment is a study of psychophysics, as it is exploring the relationship between a physical stimulus (volume on the stereo) and a psychological response (the roommate complaining). The dependent variable is at which the roommate complains, as this is the variable that is being measured and is expected to change in response to the manipulation of the independent variable (volume on the stereo).
