Randomization is one of the highly efficient methods to select the sample for the study. It holds a significant meaning in research and it would be unfair to use the word casually, without understanding its true meaning. This letter has introduced randomization and its types to guide researchers to analyze, optimize, and criticize their work in view of randomization.
