Hold sampling offers several advantages, including the ability to maintain a representative sample over time, which can lead to more accurate results. It minimizes the risk of sample bias by allowing for the collection of data under consistent conditions. Additionally, hold sampling can improve the efficiency of data collection by reducing the need for repeated sampling, ultimately saving time and resources.
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.
advantage of probability sampling

natural sampling uses what?
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
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.
Purposive sampling can allow the researcher to make generalizations about results. Purposive sampling also provides the researcher with many different sampling techniques.
