What is the relationship between a population and a sample with regard to research? A population is the set of all the individuals of interest in a particular study. A sample is a set of individuals selected from a population, usually intended to represent the population in a research study.
The study population is the subset of the target population available for study (e.g. schizophrenics in the researcher's town). The study sample is the sample chosen from the study population.

The aggregate of cases in which a researcher is interested is called a population. A sample is selection of a portion of the population to represent the entire population. Populations and Samples. Unable to study whole populations.
