randomization
(RAN-duh-mih-ZAY-shun)
- In research,
the process by which participants in clinical trials are
assigned by chance to separate groups that are given
different treatments or other interventions. Neither the
researcher nor the participant chooses which treatment or
intervention the participant will receive. Using chance to
assign people to groups means that the effects of the
treatment or intervention that participants receive can be
compared more fairly.
