Answer #1

Double blind study is a study in which neither the researchers nor the participants of the research know who is taking the treatment. It is important as it prevents bias due to demand characteristics and Placebo effect.

In a double blind study, the result can be more precise as neither the researchers nor the participants know on which sample the drug ir the treatment is working or not and who is acting as control. This gives more precise and pure results of the treatment or research. Such type of research is done in drug testing and trials.
