In social research, what is the importance of sampling? Why are probability sampling techniques superior to nonprobability sampling in achieving this end?
What will be an ideal response?
Sampling allows researchers to obtain information from a subset of a population rather than study the population as a whole which is infeasible and difficult; probability sampling allows researchers to rely on a random selection method so that the probability of selection of population elements is known; therefore, everyone in a given population are equally as likely to be chosen for the study; nonprobability sampling does not allow researchers to know in advance the likelihood of selecting each element in the population, therefore the results are less generalizable to the whole population.
