Document Summary
Sampling is common but not always necessary. Decision to take a sample of a population depends on size of population. If population is small & it is feasible to contact everyone in the population, there is no need to sample. The entire set of individuals or other entities to which study findings are to be generalized. The individual members of the population whose characteristics are to be measured. A subset of a population that is used to study the population as a whole. A list of all elements or other units containing the elements in a population. Units that contain one or more elements and that are to be listed in a sampling frame. A population selected for inclusion within a sampling frame. Random selection means selecting a sample from a larger population in which each member of the population has an equal chance of being selected for a study.
