Randomization is a process used in research and experiments to assign subjects or experimental units to different groups in a way that is determined entirely by chance. This technique is often utilized to ensure that the results of the study are unbiased and that the groups being compared are as similar as possible in all respects except for the treatment or intervention applied.
