Double Blind

An experiment is double-blind if both the participants and experimenter do not know which of the participants are in the control group.

-Using and Understanding Mathematics: A Quantitative Reasoning Approach by Bennett and Briggs (2011).


In this example, both the doctor and the patients do not now who is part of the control group or test group. This is just one example of a single blind.
