Definition of Random Sampling Random sampling, also known as probability sampling, is a technique where every member of the population has an equal (or known) chance of being selected for the sample. Using appropriate sampling techniques helps researchers generalize their findings to the broader population and reduces the risk of introducing biases that could invalidate study results. Jul 31, 2023 · Convenience sampling is a non-probability sampling method where data is collected from an easily accessible and available group of people. The individuals in the sample are selected not because they are most representative of the entire population, but because they are most easily accessible to the researcher.
