There are many advantages of using the stratified random sampling. Some of them are, ability to reduce human potential in choosing the cases in sample, statistical conclusion fro data collected, improving representation of strata etc.
stratified random sampling is a sample(strata) that a same and hemogenieous in group and that a different and heterogenious in group
Simple Random Sample Stratified Random Sampling Cluster Sampling Systematic Sampling Convenience Sampling
In stratified sampling, the population to be sampled is divided into groups (strata), and then a simple random sample from each strata is selected. For example, a state could be separated into counties, a school could be separated into grades. These would be the 'strata'.
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
Simple random sampling.
yes
No.
cheese
Yes because it gives a representation of all the data! <3

There are many such methods: cluster sampling, stratified random sampling, simple random sampling.Their usefulness depends on the circumstances.
ang hirap!
Simple Random Sample Stratified Random Sampling Cluster Sampling Systematic Sampling Convenience Sampling
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.
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
