Cluster sampling is a method of obtaining a representativesamplefrom apopulationthat researchers have divided into groups. An individual cluster is a subgroup that mirrors the diversity of the whole population while the set of clusters are similar to each other. Typically, researchers use this approac...
Cluster Sampling in Statistics The technique is widely used in statistics where the researcher can’t collect data from the entire population. So, it is the most economical and practical solution for research statisticians. Take the example of a researcher looking to understand smartphone usage in ...

we can draw a simple random sample. However, such a sample would be spread over the whole city and it would be costly to collect. Choosing a simple random sample from the blocks first keeps the sample more condensed. In many cases such block statistics are good enough. In U.S. they co...

But examples on the edge of the cluster, or near another cluster, may not be as much in the cluster as examples in the center of the cluster. This problem is addressed by the fuzzy clustering algorithms. In fuzzy clusters, an example does not belong to a given cluster, but has a ...
