In a short essay, discuss the considerations that should be made when choosing between nonprobability sampling versus probability sampling for a market research study
What will be an ideal response?
Choosing between nonprobability and probability samples is based on considerations such as the nature of the research, the error contributed by the sampling process relative to the nonsampling error, variability in the population, and statistical and operational considerations. For example, in exploratory research the findings are treated as preliminary and the use of probability sampling may not be warranted. On the other hand, in conclusive research in which the researcher wishes to generalize results to the target population, as in estimating market shares, probability sampling is favored. Probability samples allow statistical projection of the results to a target population.
