Cluster sampling can increase the complexity of the design. Investigators need to pay attention to how well the groups approximate the overall population and how homogeneous they are to each other. Bothfactorsca
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 ...
Cluster Sampling in Statistics - Learn about cluster sampling, its definition, advantages, disadvantages, and applications in statistics. Understand how to effectively implement cluster sampling methods.
Cluster sampling is much more complex to plan than other forms of sampling. Other interesting articles If you want to know more about statistics, methodology, or research bias, make sure to check out some of our other articles with explanations and examples. Statistics Student’s t-distribution ...

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 ...

In another study, Naim et al. (2014) investigated a model-based clustering technique for high-dimension datasets. Its operation is divided into three stages: multi-modal splitting, iterative weighted sampling, and uni-modality preserving merging to measure the model-based clustering approach of ...
