Definitions for "Randomized"
the process of assigning patients to different forms of treatment in a research study in a random manner
adj. Describes an experiment or clinical trial in which animal or human subjects are assigned by chance to separate groups that compare different treatments. In a randomized clinical trial, neither the researchers nor the participants can choose which group. Using chance to assign people to groups means that the groups will be similar and that the treatments they receive can be compared objectively. At the time of the trial, it is not known which treatment is best.
not ordered. a method to reduce bias in experimentation ( e.g., a randomized trial).
Making use of randomness (as in 'randomized algorithm'). This is probably an unfortunate term, since it doesn't imply that one starts with something deterministic and then 'randomizes' it. See also Monte Carlo and Las Vegas.
