When studying a large population, it is often impossible or impractical to study every single member of that population. In these cases, researchers use a sample, which is a subset of the population that is representative of the larger population. This allows researchers to draw conclusions and make inferences about the larger population based on the characteristics of the sample. A census is a complete count of all individuals in a population, but this is often not feasible due to time, cost, or other logistical constraints. A sample frame is a list of individuals in the population from which the sample is selected. A research design is the overall plan or strategy for conducting a study. Viral spread is not related to sampling methods in research.
