Stratified Random Sampling: obtained by separating the population into mutually exclusive (only belong to one set) sets, or stratas, and then drawing simple random samples (a sample selected in a way that every possible sample with the same number of observation is equally likely to be chosen) from each stratum.

There are many such methods: cluster sampling, stratified random sampling, simple random sampling.Their usefulness depends on the circumstances.
In a stratified sample, the sampling proportion is the same for each stratum. In a random sample it should be but, due to randomness, need not be.
Stratified random sampling is a form of probability sampling that provides a methodology for dividing a population into smaller subgroups as a means of ensuring greater accuracy of your high-level survey results. The smaller subgroups are called strata. Stratified random sampling is also called proportional or quota random sampling.

No.
To select random samples in statistics, you can use methods such as simple random sampling, systematic sampling, stratified sampling, or cluster sampling. Simple random sampling involves selecting individuals from a population where each has an equal chance of being chosen, often using random number generators. Systematic sampling selects every nth individual from a list, while stratified sampling divides the population into subgroups and samples from each. Cluster sampling involves dividing the population into clusters, then randomly selecting entire clusters to include in the sample.

stratified random sampling is a sample(strata) that a same and hemogenieous in group and that a different and heterogenious in group
