Probability sampling is considered the best way to obtain a representative sample, as it ensures that every member of the population has an equal chance of being included in the sample. This can increase the generalizability or external validity of the study. Random assignment, on the other hand, is a method used in experimental designs to randomly assign participants to different groups. Nonprobability sampling techniques can result in smaller samples, but they may not be representative of the population.
