Answer:
The answer is double blind experiment.
Explanation:
In a double blind experiment, neither the researchers nor the participants are aware about which group is receiving the experimental treatment. This is done in order to prevent biases in the participants' judgment (the placebo effect), and prevent the researchers from giving accidental cues.
The greatest advantage of double blind studies is they have greater reliability and validity than other types of studies.
