Advantages are:
1. Fewer investigators are needed
2. It is not so costly to obtain a sample
Disadvantages are:
1. There is the possibility of bias if, for example, only if a small number of regions are selected
2.The method is not truly random as once the final sampling areas have been selected the rest of the population cannot be in the sample.
If the population is heterogeneous, the areas chosen should reflect the full range of the diversity. Otherwise, choosing some areas and excluding others (even if it is done randomly) will result in a biased sample.

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.

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.
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.
