randomizedization
Randomizedization, also referred to as random assignment, is a process used in scientific research to allocate participants or experimental units to different treatment groups by chance rather than by choice. The technique eliminates bias, ensuring that each group is statistically comparable and that any observed effects can be attributed to the treatment itself rather than to pre-existing differences among participants.
In clinical trials, randomizedization underpins the validity of comparative studies. Participants are typically assigned using computer-generated
Beyond medical research, randomizedization is employed in agricultural experiments, psychology studies, and social science interventions to
Ethical considerations arise with randomization, particularly when a potentially superior treatment is withheld from some participants.
Statistical analysis following randomization typically involves intention-to-treat principles, preserving the initial allocation throughout analysis even if
