Study Notes

Types of Sampling

  • There are two main categories of sampling techniques: Non-Probability Sampling and Probability Sampling

Non-Probability Sampling

  • Convenience Sampling: a type of sampling where participants are selected based on convenience, such as proximity or accessibility
  • Quota Sampling: a type of sampling where participants are selected based on predefined quotas, such as age, gender, or occupation

Probability Sampling

  • Simple Random Sampling: a type of sampling where every member of the population has an equal chance of being selected
  • Systematic Sampling: a type of sampling where participants are selected at regular intervals, such as every 10th person on a list
  • Stratified Sampling: a type of sampling where the population is divided into subgroups, and participants are selected from each subgroup
  • Cluster Sampling: a type of sampling where groups or clusters of participants are selected, rather than individual participants
