Collecting data from populations requires making observations of every single member of the population, which is often not feasible due to logistical and financial constraints. Therefore, researchers generally collect data from a smaller subset of the population, which is known as a sample. This sample is intended to be representative of the population and can be used to make inferences about the population as a whole.
