Random sampling in research methodology

Random sampling is one of the most popular types of random or probability sampling. Cluster random sampling offers an overview of sampling methods for quantitative research and contrasts them with qualitative method for further understanding. Cluster sampling is very different from stratified sampling with cluster sampling one should divide the population into groups (clusters) obtain a simple random sample of so many clusters from all possible clusters obtain data on every sampling unit in each of the randomly selected clusters.

Random sampling is a critical element to the overall survey research design this entry first addresses some terminological considerations second, it discusses two main components of random sampling: randomness and known probabilities of selection.

  • Stratified random sampling intends to guarantee that the sample represents specific subgroups or strata accordingly, application of stratified sampling.
  • Method: best when: simple random sampling: whole population is available stratified sampling (random within target groups) there are specific sub-groups to investigate (eg demographic groupings) systematic sampling (every nth person) when a stream of representative people are available (eg in the street.

In statistics, quality assurance, and survey methodology, sampling is concerned with the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population.
