A random sample is a method of selecting a subset from a larger statistical population such that every member has an equal and known probability of inclusion. Its parameters: (1) defined population, (2) random selection mechanism (random number generator, lottery method), (3) known inclusion probabilities. It persists through statistical textbooks, research methodology standards, and quality assurance protocols.
