What type of study is a randomized controlled trial?
Randomized controlled trials (RCT) are prospective studies that measure the effectiveness of a new intervention or treatment. Although no study is likely on its own to prove causality, randomization reduces bias and provides a rigorous tool to examine cause-effect relationships between an intervention and outcome.
What is randomization research?
(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.

Fisher was clearly the progenitor of randomization as an integral part of rigorous comparative experimentation, although the idea had already been broached by others such as CS Peirce, the 19th century American philosopher.
