The purpose of random sampling is to ensure that research participants constitute a representative sample from the population of interest. This means that the sample should reflect the characteristics of the population as a whole, and that any differences or variations in the sample should be due to chance rather than systematic bias. By using random sampling techniques, researchers can increase the likelihood that their results will be generalizable to the larger population, and avoid the problem of sampling bias.
