A stratified random sample is a variation on the simple random sample that guarantees that the distribution of the sample will exactly reflect the population on whatever characteristic is used to Stratified sampling can improve your research, statistical analysis and decision-making. Stratified sampling is a process that first divides the overall population into separate subgroups and then creates a sample by drawing subsamples from each of those subgroups. Stratified sampling is based on the idea of obtaining, as a result of controlling certain variables, a sample that recreates an image that is as close as possible to the population.

Within the overall process When sociologists decide on a sampling method, the aim is usually to try and make it as representative of the target population as possible. The target population's elements are divided into distinct groups or strata where within each Sample selection is said to be stratified if some form of random sampling is separately applied in each of a set of distinct groups formed from all of the entries on the sampling frame from which the sample is The main difference is that in stratified sampling, you draw a random sample from each subgroup (probability sampling).
