But previous Pew Research Center analyses have demonstrated how surveys that use nonprobability sampling may have errors twice as large, on average, as those that use probability sampling. The Purpose of Sampling. Evaluating sampling procedures helps determine if there is sampling bias, which can skew results and affect conclusions. [4][5] For example, many surveys have substantial amounts of nonresponse. Cluster sampling is best used to study large, spread-out populations, where aiming to interview each subject would be costly, time-consuming, and perhaps impossible. Probability sampling, for example, stratified and cluster sampling, is thus fundamental in those studies that tend to make statistically significant inferences about the wider population. Understand how it differs from probability sampling and its applications in research. Stratified Sampling: A method where the population is divided into subgroups (strata) and random samples are taken from each stratum to ensure representation of all groups. There are many methods for sampling, each with a slightly different purpose.
