- The process by which an outcome is determined solely by chance, for example, by a coin flip. A randomized controlled trial is a clinical trial that involves at least one test treatment and one control treatment and in which the treatments to be administered are selected by a random process, such as the use of a random-numbers table. The opposite of random is nonrandom.
* * *Governed by chance; used of a process in which the outcome is indeterminate but may assume any of a set of values (the domain) with probabilities specifiable in advance. While the r. process is widely used in probability theory, empiric justification for the term is more complicated. The minimum requirement is that repeated realization of the process will settle down to a stable distribution or, if not metrical, a stable set of frequencies if the trait is classifiable only. See r. mechanism. [M.E. randon, speed, errancy, fr. O. Fr. randir, to run, fr. Germanic]
* * *ran·dom (ranґdəm) [Old French randon violence] pertaining to a chance-dependent process, particularly one that occurs according to a known probability distribution.
