Randomized Controlled Trial (RCT) / Randomized Field Experiment

Refers to an experimental research design in which participants are randomly assigned to a treatment or a control group. Most social scientists consider random assignment to lead to the highest level of confidence that observed effects are the result of the program and not other variables.


Millions of cases are filed in local, state, tribal, and federal courts each year. Most court systems include trial courts, which hear criminal and civil cases; appellate courts, which review cases decided at the trial court level; and at least one supreme court, which is the court of last resort within a judiciary system.
