Detailed explanation-1: -A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results.
Detailed explanation-2: -Another technique for the control of experimenter effects is to minimize contact between the experimenter and the participant. The less exposure a subject has to experimenters, the less likely it is that cues from the experimenter will be “picked up” by the respondent.
Detailed explanation-3: -In a single-blind experiment, participants do not know which group they have been placed in until after the experiment has finished. Example: Single-blind vaccine study You have developed a new flu vaccine.
Detailed explanation-4: -To control possible experimenter effects, while also controlling participant expectations, researchers may use a procedure in which neither the participant nor the researcher interacting with the participants knows which participants are in the experimental or control conditions.
Detailed explanation-5: -A single-blind study occurs when the participants are deliberately kept ignorant of either the group to which they have been assigned or key information about the materials they are assessing, but the experimenter is in possession of this knowledge.
