What is the process for conducting a randomized selection for participants in the study?

The process for conducting a randomized selection for participants in a study involves assigning individuals to different groups by chance, rather than by choice or bias. This helps ensure that the study results are not influenced by any preconceived notions or preferences. Randomization can be done using computer-generated random numbers, random drawing, or other methods to ensure that each participant has an equal chance of being selected.
