| double blinded dohri gopniyata vaala
Explanation:
दोहरी गोपनीयता वाला
In a double-blind experiment, neither the individuals nor the researchers know who belongs to the control group. Only after all the data are recorded (and in some cases, analyzed) may researchers be permitted to learn which individuals are which. Performing an experiment in double-blind fashion is a way to lessen the influence of prejudices and unintentional physical cues on the results.

In a single-blind trial/experiment, only the individual subjects do not know whether they are so-called \"test\" subjects or members of an \"experimental control\" group. In such a trial there is a risk that subjects are influenced by interaction with the researchers - known as the experimenter effect.
