Randomization in research ensures fairness by providing equal chances of selection, maintains external validity, and helps in avoiding bias.
Randomization plays a crucial role in research by ensuring that external validity is maintained, allowing inferences to be generalized from the sample to the entire population. It helps in avoiding bias by randomly assigning subjects or treatments so that unknown confounders are accounted for. Additionally, randomization ensures that each member of the population has an equal probability of being selected, enhancing the fairness of the study.
