Sampling is the process of selecting a subset of individuals or items from a larger population to make inferences about the whole population. It is a crucial step in empirical studies as it helps researchers gather data efficiently and effectively.

Probability Sampling Techniques

  • Simple Random Sampling: In this technique, each member of the population has an equal chance of being selected.
  • Stratified Sampling: The population is divided into subgroups or strata, and samples are randomly selected from each stratum.
  • Cluster Sampling: The population is divided into clusters, and a random sample of clusters is selected for data collection.
  • Systematic Sampling: Researchers select every nth member from the population to form a sample.

Non-Probability Sampling Techniques

  • Convenience Sampling: Participants are chosen based on their availability and accessibility to the researcher.
  • Purposive Sampling: Researchers select participants based on specific criteria relevant to the study.
  • Snowball Sampling: Existing participants refer other potential participants, creating a chain of referrals.

Factors to Consider When Choosing a Sampling Technique

  • Population Size: The size of the population can influence the choice of sampling technique.
  • Research Objectives: The goals of the study and the type of data needed play a role in determining the sampling technique.
  • Resource Constraints: Time, budget, and human resources available for data collection can impact the sampling method chosen.
  • Level of Precision: The desired level of accuracy and precision in the study results can guide the selection of a sampling technique.

Data Collection Tools and Instruments

Data collection tools and instruments play a vital role in empirical research by helping researchers gather accurate and reliable data.
