natural sampling uses what?
You can't conduct startified sampling if there are no difinative groups, thus systematic sampling is more efficient if your data has no groups.
Yes, if under simple random sampling there are likely to be too few representatives from a certain subset of the population in which you might have an interest.
Using sample that does not match the population
1).There may errors (Producer's and Consumer's risk) associated with the sampling. 2).The sample does not provide 100% accurate information of the condition of the bacth.
Advantages of multistage sampling?
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
advantages of multiphase sampling
There are many advantages and disadvantages of sampling. These advantages include being able to try what you need before you buy.

natural sampling uses what?
Sampling allows researchers to collect data from a smaller subset of a population, saving time and resources. It can provide insights into the characteristics of a larger population without having to survey everyone. Additionally, sampling can reduce bias in data collection and improve the overall quality of research findings.
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.
efficiency
Snowball sampling allows for the recruitment of hard-to-reach populations, such as marginalized or hidden communities. It is particularly useful for studying groups where there is no defined sampling frame. Additionally, it can help build trust and rapport with participants as referrals come from within the community.
Advantages of cluster sampling include that it's inexpensive, fast, and simple. A disadvantage is that it is known to have a high sampling error.
