Detailed explanation-1: -A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over. This makes results of the study less likely to be biased.
Detailed explanation-2: -Example of Double Blinding in Research In these studies, random assignment is used to allocate patients into two groups: the treatment/experimental group (which receives the drug) and the control group (which receives an inactive substance that looks identical to the treatment but has no drug in it).
Detailed explanation-3: -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-4: -A double-blind study withholds each subject’s group assignment from both the participant and the researcher performing the experiment. If participants know which group they are assigned to, there is a risk that they might change their behavior in a way that would influence the results.
Detailed explanation-5: -Which of the following statements describes a double-blind experiment? Neither subjects nor researchers know which subjects are in the control or experimental groups.
