Key Points

  • Cluster Sampling
    • Involves grouping the selected population and choosing the groups.
    • Useful when the population is large and spread over a wide area.
  • Sequential Sampling
    • Characterized by no advance ascertainment of the final sample size.
    • Samples are evaluated sequentially, and sampling continues until sufficient data is gathered.
  • Stratified Sampling
    • Involves selecting a representative sample when a population is a heterogeneous group.
    • Ensures that different sub-groups are adequately represented.
  • Quota Sampling
    • Involves choosing the sample based on judgement to meet a predefined quota.
    • Often used in market research to ensure certain characteristics are represented.

Additional Information

  • Sampling Techniques Overview
    • Cluster Sampling
      • Used when it is difficult to conduct random sampling due to geographic constraints.
      • Groups or clusters are selected, and all members of the chosen clusters are included in the sample.
    • Sequential Sampling
      • Effective in quality control processes where items are tested sequentially.
      • Sampling continues until a stopping rule is met, such as reaching a certain number of defective items.
    • Stratified Sampling
      • Ensures that specific subgroups within a population are represented proportionally.
      • Useful in surveys where different segments of the population may have different characteristics.
    • Quota Sampling
      • Non-probability sampling method where the researcher selects samples based on specific quotas.
      • Quotas are often based on demographic characteristics such as age, gender, or income.
