survey sampling techniques

Survey sampling techniques involve selecting a group of people or items from a larger population to represent that population in a study. Common methods include random sampling, where everyone has an equal chance of being chosen; systematic sampling, selecting at regular intervals; stratified sampling, dividing the population into subgroups and sampling within them; and cluster sampling, choosing entire groups or clusters randomly. These techniques help ensure that survey results are accurate and reflect the views or characteristics of the whole population, making data collection more efficient and reliable.
