Quizplus · Accepted Answer

Dr. Abdul has engaged in random sampling, as he has ensured that every student has an equal chance of being a participant. This type of sampling helps to increase the generalizability of research findings to the population being studied. Biased sampling would involve intentionally selecting participants who are not representative of the population, whereas operational sampling refers to the methods used to measure or manipulate a variable in a study. Representative sampling is a broader term that refers to the extent to which a study's sample reflects the characteristics of the population being studied.
