the combinitoin of any random samples is called multistage samplinag.
it is the expensive form of cluster samling. when each elements in cluster are expensive then we use multistage sampling.
A good example to panel sampling will be sampling the performance of a group of companies in a specified region. This way they the samples can be revisited at a later stage thus panel sampling.
stratified random sampling is a sample(strata) that a same and hemogenieous in group and that a different and heterogenious in group
Circular systematic sampling is a random sampling method. An example is random sampling of households. Assume that a random number generator provides the number 49 as a starting point. Starting with the household that is 49 on the target list, every nth household on the list would be sampled until the desired sample size is reached
You are correct; convenience sampling is not random 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 of multistage sampling?
Multistage sampling is a form of cluster sampling where instead of using the entire cluster, random samples from each cluster are used. This is typically used when doing opinion polls or surveys.

Oh, dude, like, multiphase sampling is when you have different phases within one stage, while multistage sampling is like a multilevel marketing scheme where you have different stages with different samples. So, like, multiphase is more about breaking down one big stage into smaller phases, and multistage is about moving through different stages to get your final sample. Hope that clears things up for you!
Sampling techniques in researching involves to types of sampling. The probability sampling and the non-probability sampling. Simple random is an example of probability sampling.
A good example to panel sampling will be sampling the performance of a group of companies in a specified region. This way they the samples can be revisited at a later stage thus panel sampling.
List the reasons for sampling
Standing in a shooping mall and selecting people as they walk by to fill out a survey is an example of convenient sampling.
For decades the go to place to find the best quality reviews on pretty much any product in the US has been consumerreports.org. Consumer reports has been around for forever, and they review products that come onto the market and give pretty solid objective reviews. They can help make your decision easier.
a multistage rocket is a rocket. a rocket could be a multistage rocket. all multi-stage rockets are rockets, but not all rockets are multi-stage. For example the space misstions. They are all multi staged, but each stage is a rocket on its own.
