 Population sampling refers to the process through which a group of representative individuals is selected from a population for the purpose of statistical analysis. Performing population sampling correctly is extremely important, as errors can lead to invalid or misleading data. There are a number of techniques used in population sampling to ensure that the individuals can be used to generate data which can in turn be used to make generalizations about a larger population.
