Cluster sampling is the most economically efficient sampling technique when the primary sampling unit is a large cluster of elements rather than individual elements. This technique reduces time and cost because the sampling is performed on a cluster of elements, which requires fewer resources than selecting individual elements. Stratified sampling is used when the population has distinct subgroups, grouped sampling is used to create ranging categories, and homogeneous sampling is used when the population is similar in characteristics. None of these techniques are specifically designed for being economically efficient.
