In a short essay, discuss the difference between nonprobability sampling and probability sampling. Include a specific example of each type of sampling to support your answer
What will be an ideal response?
a. Nonprobability sampling relies on the personal judgment of the researcher, rather than chance, in selecting sample elements. The researcher may select the sample arbitrarily, based on convenience, or make a conscious decision about which elements to include in the sample. Examples of nonprobability sampling include interviewing people at street corners, in retail stores, or in the malls. While nonprobability sampling produces good estimates of population characteristic, these techniques are limited. There is no way to objectively evaluate the precision of the sample results.
b. In probability sampling, sampling elements are selected by chance, that is, randomly. The probability of selecting each potential sample from a population can be prespecified. While every potential sample need not have the same probability of selection, it is possible to specify the probability of selecting a particular sample of a given size. An example of a probability sample is a randomly drawn lottery. Confidence intervals can be calculated around the sample estimates, and it is meaningful to statistically project the sample results to the population, that is, draw inferences about the target population.
