Single-Blind Research Method

The Single-Blind research method is a specific research procedure in which the researchers (and those involved in the study) do not tell the participants if they are being given a test treatment or a control treatment. This is done in order to ensure that participants don't bias the results by acting in ways they "think" they should act. For example, if a participant believed they were in the group that received a sleeping drug, they may report that they are tired because they believe they "should be tired" since they're in the sleeping drug group.
