randomisation

Randomization is a process used in experiments to assign subjects or items to different groups in a way that is unpredictable and unbiased. This means that each participant has an equal chance of being placed in any group, which helps ensure that differences between groups are due to the treatment or condition being tested, rather than other factors. By removing selection bias, randomization increases the reliability of the results, making it more likely that the findings accurately reflect the true effect of the intervention or variable under study.
