A stratified random sample is one obtained by dividing the population elements into mutually exclusive non-overlapping groups of sample units called strata then selecting a simple random sample from within each stratum stratum is singular for strata.
Stratification of target populations is extremely common in survey sampling. In this type of sampling we divide the populations into certain classes or categories on the basis of their characteristics features such as gender age etc. It is theoretically possible albeit unlikely that this would not happen when using other sampling methods such as simple random sampling. Stratified random sampling is a method for sampling from a population whereby the population is divided into subgroups and units are randomly selected from the subgroups.

What is Stratified Sampling.
There are two types of sampling analysis. The strata is formed based on some common characteristics in the population data. A stratified sample includes subjects from every subgroup ensuring that it reflects the diversity of your population. A stratified random sample is a population sample that requires the population to be divided into smaller groups called strata. How do you find percent in stratified random sampling. Ensuring the diversity of your sample.
