Members of the experimental and control groups are usually selected using randomization techniques to eliminate bias and increase the reliability of the results. This ensures that the two groups are as similar as possible before any treatment or manipulation is introduced, and any differences that emerge can be attributed to the treatment rather than to pre-existing differences between the groups. Probability and representative samples are also important considerations, but randomization is the most crucial method for selecting participants in an experiment. Sampling frames are used to create a list of potential participants, but they do not actually select individuals for the experimental or control groups.
