randomization

Randomization is a method used to ensure fairness and mitigate bias in experiments or studies. By randomly assigning subjects or participants to different groups, researchers can isolate the effects of a specific variable and minimize the influence of outside factors. This process helps ensure that the groups are similar and that the results can be attributed to the variable being tested rather than pre-existing differences. In essence, randomization promotes reliability and validity in findings by ensuring that any observed effects are due to the treatment or condition applied, rather than chance or external influences.
