What is the different between single blind study and double blind study?
In a single blind study, the subject being studied does not know whether he is part of the experimental group or control group, but the researcher recording the results does know. In a double blind, neither the subject nor the observer knows to which group in the experiment the subject belongs.
Why might a double-blind study yield more reliable results than a single-blind study?
In single blind studies, the experimenter (or observer) is aware of who or what belongs to the control group and the experimental group.In double blind studies, the experimenter is not aware of who/what belongs to which group. This is to eliminate the subjective bias an experimenter may have.

What is a blind trial?
A blind trial is a trial in which the subject does not know if he is part of the experimental group or the control group. In the case of a pharmaceutical trial, a blind study would be one in which the patients participating in the study would not know if they were being given the actual drug or a placebo. A double-blind trial is one in which neither the patients nor the doctors involved in the study know which patients are in the control group and which patients are in the experimental group.
Why is double blind study reliable?
To avoid the placebo effect! If doctor knows that the substance he is giving is inert, his behavior will change. Patient is likely to note the same. If the doctor knows that he is giving the drug, his behavior will be confident. Patient will again note the same. So to avoid this placebo effect, the doctor has to be blind as well. Same is true for the patient also. So both the patient and the doctor need to be blind to have the proper study of the drug. Such study is called as double blind study and it is necessary for proper results.
