Most trials of new medical treatments, and most other trials for that matter, now implement some form of randomisation. The idea sounds so simple that defining it becomes almost a joke: randomisation is “putti…

How does one design a study, keeping in mind the importance of randomization for our ability to generalize and assign causation? This is a part of epidemiology which strives to detect whether clusters of disease are related to …
Random Assignment in Experiments
In experimental research, random assignment is a way of placing participants from your sample into different treatment groups using randomization. With simple random assignment, every member of the sample has a known or …
Randomized experiment
In science, randomized experiments are the experiments that allow the greatest reliability and validity of statistical estimates of treatment effects. Randomization-based inference is especially important in experimental design and in survey sampling.
A roadmap to using randomization in clinical trials
Randomization is the foundation of any clinical trial involving treatment comparison. It helps mitigate selection bias, promotes similarity of treatment groups with …
Why randomize?
Random assignment controls for both known and unknown variables that can creep in with other selection processes to confound analyses. Randomized experimental design is a powerful tool …
Principles and methods of randomization in research
Randomization is an important technique in research because, when accomplished successfully, it not only removes potential personal bias from research but also …
Single-case experimental designs: the importance of …
We emphasized the importance of incorporating an element of randomization in the study design for internal and statistical conclusion validity, including dealing with missing data.
