Question

Quizplus · Accepted Answer

Tess is sleeping in a laboratory, which indicates that the study is a laboratory observation. A double-blind study involves both participants and researchers being unaware of the treatment being administered, and a single-blind study involves only the participants being unaware. Naturalistic observation involves observing behavior in a natural setting, which is not the case in this scenario.
