A statistician, or anyone who wants to ensure that, for a population that can be divided into a set of strata, the sample is forced to contain the same proportion from each stratum.

Nothing! there the same
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.
No.
it can be used when members of the population are heterogenous
Analyzing 20% of the items that are under $25,000
semi stratified sampling

stratified random sampling is a sample(strata) that a same and hemogenieous in group and that a different and heterogenious in group
stratified sampling technique
The main difference between the quota and stratified sampling is that in the stratified sampling the researcher can not select the individuals to be included in the sample (he doesn't have control over who will be in the simple), but in the quota sampling the researcher has control over who will be in the sample (he can contact certain people and include them in the sample).
