A <u>double-blind experiment </u>allows researchers to identify the specific effects of the independent variable from the possible effects of the experimenter's and the participants' expectations about it.
<u>Explanation</u>:
The double-blind experiment is conducted to ensure that the results of the experiments are not biased. The double-blind study states that the person who is implementing the experiment and the person involved in the experiment are not aware of each other. So there will be no bias in the experimental treatment.
The reliability in the double-blind experiment is improved. Under this experiment unintentional tipping off the study participants and biasing of the evaluation results by the researchers can be avoided.
