Randomization technique is used to randomly assign participants to either the experimental or control group, ensuring that both groups are equal and that any differences in the results can be attributed to the experimental treatment. A sampling frame, representative sample, and probability sample are terms used in sampling methods and are not directly relevant to the selection of experimental and control groups.
