Randomization is the process by which each participant has the same chance of being assigned to either intervention or control.
Randomization as a method of experimental control has been extensively used in human clinical trials and other biological experiments. It prevents the selection bias and insures against the accidental bias. It produces the comparable groups and eliminates the source of bias in treatment assignments.
Randomization in an experiment means random assignment of treatments. This way we can eliminate any possible biases that may arise in the experiment. Randomization in an experiment is important because it minimizes bias responses.
