Quizplus · Accepted Answer

In a single-blind study, the participants are unaware of whether they are in the control group or the experimental group, but the experimenter knows. This is in contrast to a double-blind study, where both the participants and the experimenter are unaware, and a triple-blind study, where the participants, experimenter, and data analyst are unaware. A placebo is a substance or treatment given to the control group in order to account for the placebo effect, but it is not directly related to blinding.
