Single Stage Cluster Sampling: The researcher performs sampling just once. It is a technique of sampling wherein each element of the chosen cluster is observed for testing purposes. Such a technique is not preferred when the population is large, and the clusters are too big to be included full...
What is Cluster Sampling? In cluster sampling, you split the population into groups (clusters), randomly choose a sample of clusters, then measure each individual from each selected cluster. The most common and obvious example of cluster sampling is when school children are sampled. An example I...

Another centroid based approach to K-means is K-medoids. Medoids are representative objects of a dataset or a cluster within a dataset whose sum of distances to other objects in the cluster is minimal. Instead of having an arbitrary centroid be the center of the graph, the algorithm creates ...
The individuals in cluster groups are different whereas the individuals in stratified sampling subgroups are the same due to a shared characteristic. The primary goal of cluster sampling is to make it easier to gather data. Important Even with a well-chosen sample, there's a risk ofsampling err...

Multistage sampling.This approach is a more complicated form of cluster sampling. It divides the larger population into multiple clusters and then breaks those clusters into second-stage clusters, based on a secondary factor. The secondary clusters are then sampled and analyzed. This staging could co...
