What is survey sampling?

Survey sampling is a statistical process used to select a subset of individuals or items from a larger population to estimate characteristics of the whole group. This method allows researchers to gather data efficiently and cost-effectively without surveying every member of the population. Different sampling techniques, such as random sampling, stratified sampling, and cluster sampling, help ensure that the sample is representative and that the results are reliable. Survey sampling is widely used in fields like market research, public health, and social sciences to draw meaningful conclusions from data.
