Stratified sampling involves dividing a population into distinct subgroups, or strata, that share similar characteristics, such as age, income, or education level. Once the strata are defined, researchers randomly sample from each subgroup in proportion to its size relative to the entire population. This method ensures that all subgroups are adequately represented, leading to more accurate and reliable results. It is particularly useful when researchers want to ensure that specific segments of the population are included in the sample.

What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
Breifly explain three different examples of sampling?
simple random, stratified sampling, cluster sampling
What are the differences between systematic and stratified sampling?
Nothing! there the same
How do you select random samples in statistics?
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.
Are random sampling and stratified sampling one and same?
No.
When is it appropriate to use stratified random sampling?
it can be used when members of the population are heterogenous

How is simple random sampling and stratified sampling related?
ang hirap!
What is the difference between quota and stratified sampling?
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).
