randomisation
The scientist uses randomisation to assign the test subjects to different groups.
Noun: 1. The process or act of making something random: Specifically, the deliberate arrangement or selection of items, subjects, or data in a haphazard, unsystematic way to eliminate bias and simulate chance. It is a fundamental principle in experimental design and statistical sampling.
Randomisation is primarily used in formal, academic, and scientific contexts, particularly in statistics, experimental research, clinical trials, and survey methodology. It describes a controlled technique to ensure impartiality. - The randomisation of participants into control and treatment groups is essential for a valid clinical trial. - Researchers used computer-generated randomisation to assign the survey samples.
- The study's credibility depended on the proper randomisation of the test subjects.
- Randomisation helps ensure that each item has an equal probability of being chosen.
- A common method for randomisation is using a random number generator.
- Block randomisation: A technique used in clinical trials to ensure balanced group sizes at any point during the study.
- Stratified randomisation: The process of randomising subjects within specific subgroups (strata) to ensure these subgroups are proportionally represented in all trial arms.
- "The randomisation was broken": A phrase indicating that the intended random allocation was compromised, potentially biasing the results.
- Randomise (verb, chiefly British English): To make random.
- Randomization (noun, chiefly American English): The American English spelling of .
- Random (adjective): Having no definite pattern or purpose; governed by chance.
- Randomiser (noun): A tool or algorithm that performs randomisation.
- Randomization
- Random assignment
- Random allocation
- Haphazardization (rare, technical)
- Randomised controlled trial (RCT): A study in which participants are randomly assigned to either a treatment or control group, considered the gold standard for clinical research.
- At random: Without method or conscious decision.

- a deliberately haphazard arrangement of observations so as to simulate chance
