SAMPLING TECHNIQUE Meaning and
Definition
-
A sampling technique, in the context of research or statistics, refers to the systematic method employed to select a representative group or subset of individuals or elements from a larger population. The primary purpose of using a sampling technique is to derive accurate and reliable conclusions about the whole population based on information gathered from the selected sample.
Sampling techniques are essential in research as well as in statistical analysis, where it may be impractical or impossible to collect data from an entire population due to limitations like time, resources, or feasibility. These techniques involve carefully selecting a sample group that adequately represents the characteristics, traits, or attributes of the overall population to ensure the generalizability and validity of the findings.
Various sampling techniques exist, each with its own benefits and suitability depending on the research objectives and constraints. Some commonly used techniques include simple random sampling, stratified sampling, cluster sampling, systematic sampling, and convenience sampling.
In simple random sampling, each member of the population has an equal and independent chance of being selected. Stratified sampling divides the population into homogeneous subgroups or strata before selecting a proportional sample from each group. Cluster sampling involves dividing the population into clusters or naturally occurring groups and selecting samples from these clusters. Systematic sampling involves selecting every nth individual from the population after a random starting point. Convenience sampling involves choosing participants who are readily accessible or available to the researcher.
Correctly employing an appropriate sampling technique is crucial to avoid bias and ensure that the selected sample accurately represents the entire population, leading to reliable and valid research findings.

Etymology of SAMPLING TECHNIQUE
The word "sampling" originated from the Old French term "essample" which means "example" or "model". It can be traced back to the Latin word "exemplum" with a similar meaning. The word "technique" comes from the Latin word "technicus", derived from the Greek word "tekhnē", meaning "art" or "craft". When combined, "sampling technique" refers to the method or approach used to select samples or representative examples from a larger population for research or analysis purposes.
