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.

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 experimental protocol has the most reliable results?
Double blind
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.
What does a double blind study mean?
A double-blind study is a research design where neither the participants nor the researchers know who is receiving the treatment and who is receiving a placebo. This helps to reduce bias in the study results by preventing expectations from influencing the outcomes.
When a study is designed so that neither the subjects nor the experimenters know which subjects are in the treatment group and which ones are in the control group the study is called a experime?
The study is called a double-blind study. This helps to reduce bias and ensure that the results of the study are not influenced by the expectations or beliefs of either the subjects or the experimenters.
What kind of study is it when neither the experimenter nor the participants know who is in the control group and who is in the experimental group?
This type of study is known as a double-blind study. It helps to minimize bias by ensuring that neither the experimenter nor the participants can influence the results based on their expectations or knowledge of who is in each group.
A clinical experiment is designed in such a way that neither the researchers dispensing a treatment nor the persons in the experimental or control groups know if they're getting a sugar pill or a new?
This type of study design is called a double-blind experiment. It helps to minimize bias and ensure that the results are not influenced by the expectations or beliefs of the researchers or participants. By keeping both parties unaware of who is receiving the treatment, the study results are considered more reliable and trustworthy.
What kind of study doesn't tell the participants or the researchers which group is is the control or experimental group?
Double blind.
What is the name of the study where neither the researchers nor the participants know who is getting the real treatment?
double blind
What are the disadvantage of a double blind study?
Some disadvantages of a double-blind study include increased complexity and cost due to the need for additional measures to maintain blinding, potential challenges in implementing blinding in certain study designs or interventions, and the possibility of unblinding if not carefully managed, which could introduce bias into the results.
When is a double-blind study not possible?
A double blind surgery is not possible when the medical intervention a patient is getting cannot be kept from them, such as a surgery. Both the scientist and the participant in the trial know exactly what the participant is getting done in the trial.
