What is the difference between a single blind and double blind experiment?
Hereof, what is a double blind experiment and what is the advantage it has over a single blind experiment?
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. Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect.
Subsequently, question is, what is double blind testing? Definition of double-blind. : of, relating to, or being an experimental procedure in which neither the subjects nor the experimenters know which subjects are in the test and control groups during the actual course of the experiments — compare open-label, single-blind.
Additionally, what does a single blind study mean?
Definition of single-blind. : of, relating to, or being an experimental procedure in which the experimenters but not the subjects know the makeup of the test and control groups during the actual course of the experiments — compare double-blind, open-label.
Why might a double blind study yield more reliable results than a single blind study?
Largely because it reduces the potential of bias interfering with the result of the study. To explain, a double blind study is a type of randomized control trial which in turn is a trial testing the efficacy of a new drug or therapeutic measure against a placebo or preexisting drug.
