Purposeful Sampling

  • Extreme, Typical, Critical, or Deviant Case: Rare

  • Intensity: Depicts interest strongly

  • Maximum Variation: range of nationality, profession

  • Homogeneous: similar sampling groups

  • Stratified Purposeful: Across subcategories

  • Mixed: Multistage which combines different sampling

  • Sampling Politically Important Cases

Purposeful Sampling

  • Purposeful Random: If sample is larger than what can be handled & help to reduce sample size

  • Opportunistic Sampling: Take advantage of new opportunity

  • Confirming (support) and Disconfirming (against) Cases

  • Theory Based or Operational Construct: interaction b/w human & environment

  • Criterion: All above 6 feet tall

  • Purposive: subset of large population – high level business

    Snowball Sample (Chain-Referral): picks sample analogous to accumulating snow

Advantages of Sampling

  • Increases validity of research

  • Ability to generalize results to larger population

  • Cuts the cost of data collection

  • Allows speedy work with less effort

  • Better organization

  • Greater brevity

  • Allows comprehensive and accurate data collection

  • Reduces non sampling error. Sampling error is however added.
