Stratified Sampling Method. A stratified random sample is a sampling technique that falls under the random sampling method. Stratified sampling, also sometimes called quota sampling, is akin to systematic sampling in that a predetermined number of samples are taken from each of the m subregions, but the method of selection nm is quite different.
In this ed method, the input space is partitioned in different “strata,” and a representative value is selected from each stratum. Stratified sampling is a method of random sampling where researchers first divide a population into smaller subgroups, or strata, based on shared characteristics of the members and then randomly select among these groups to form the final sample. Unlike other sampling methods, such as simple random sampling (srs), stratified sampling ensures that members of the population with specific characteristics will be represented within the sample.
The Strata Is Formed Based On Some Common Characteristics In The Population Data.

Randomly Sample From Each Stratum.
A stratified random sample is a sampling technique that falls under the random sampling method. Stratified random sampling (usually referred to simply as stratified sampling) is a type of probability sampling that allows researchers to improve precision (reduce error) relative to simple random sampling (srs). Stratified sampling, also sometimes called quota sampling, is akin to systematic sampling in that a predetermined number of samples are taken from each of the m subregions, but the method of selection nm is quite different.

Researchers use the stratified method of sampling when the overall population size is too large to get representative sample units for every needed subpopulation. It also helps them obtain precise estimates of each group’s characteristics. Therefore stratified random sampling provides a higher degree of precision than simple random sampling random sampling random sampling, or probability sampling, is a sampling method that allows for the randomization of sample selection.
