Statistical sampling is a method used to select a subset of individuals or items from a larger population to make inferences about that population. By studying this smaller group, researchers can gather insights without needing to examine every single member. This approach saves time and resources while still providing valuable information. There are various techniques for statistical sampling, such as random sampling, where each member of the population has an equal chance of being chosen, and stratified sampling, which involves dividing the population into distinct subgroups. These methods help ensure that the sample accurately represents the larger population, leading to more reliable results.
