Cluster Sampling: to reduce work for dispersed population

Used to check the reliability of previously conducted survey.

Multistage Sampling: In multistage sampling, chosen clusters are again resampled.

  • In multistage sampling, clusters are usually selected using some form of random sampling.

  • Carried out in many steps.

  • Information gathered from last stage

Multiphase Sampling: gathers some information from a large sample and more detailed information from subsamples within this sample.

Narrowing down previous sample size based on screening tests at every level. Choices are purposeful, and the tests at each stage give meaningful information
