RERANDOMIZATION Meaning and
Definition
-
Rerandomization is the process of randomly assigning subjects to different treatment groups in a scientific study or experiment after an initial randomization has been conducted. It is a statistical technique that aims to minimize bias and increase the validity of the study by reassigning subjects to different groups, ensuring an even distribution of participants across the various treatment conditions.
The primary objective of rerandomization is to address potential confounding factors that may have influenced the initial randomization assignment. By introducing reassignment and redistributing subjects, rerandomization helps to eliminate any systematic differences or imbalances that may have occurred during the original randomization and could potentially affect the study's accuracy and reliability.
This technique is particularly useful in clinical trials and other randomized controlled studies, where ensuring unbiased treatment allocation is crucial for evaluating the effectiveness of interventions. Rerandomization allows researchers to reassess the effects of the treatments and accurately determine their impact, as the new random assignment helps ensure that any observed differences between the treatment groups are solely due to the interventions under investigation and not influenced by any confounding factors.
Overall, rerandomization is a statistical approach employed to strengthen the design of randomized experiments, reducing bias and enhancing the credibility of the study's findings. By applying this technique, researchers aim to improve internal validity, enabling more accurate conclusions about causal relationships within the study population.

Etymology of RERANDOMIZATION
The word "rerandomization" is formed by combining the prefix "re-" meaning "again" or "back" and the word "randomization" which refers to the process of assigning participants to different treatment groups or conditions randomly. Therefore, "rerandomization" essentially means to randomize or assign participants to groups again.
The etymology of "randomization" comes from the word "random", which originated in the late 16th century from the Old French word "randir" meaning "to run". It was used to describe someone who ran in a disorderly manner or without a specific purpose. Over time, "random" came to mean unpredictable or haphazard. The suffix "-ize" that can be found in "randomization" is used to indicate the action or process of making something random.
