Question

Quizplus · Accepted Answer

Random assignment is the best choice in this scenario because it allows the researcher to randomly assign participants to different groups, ensuring that they are as similar as possible at the beginning of the experiment. Random sampling is used to select participants from a population, self-report methods involve participants reporting on their own behavior or experiences, and participant observation involves observing participants in their natural environment. While all of these methods may be useful in certain research contexts, none of them address the specific goal of creating similar groups at the beginning of an experiment as well as random assignment does.
