Cluster sampling is a method of obtaining a representative sample from 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 app...

Cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research. So, researchers then select random groups with a simple random or systematic random sampling technique for data collection and unit of analysis. Example: A researcher...

In cluster sampling, instead of selecting all the subjects from the entire population right off, the researcher takes several steps in gathering his sample population.
Why is cluster sampling used? Cluster sampling is typically used in market research. It's usedwhen a researcher can't get information about the population as a whole, but they can get information about the clusters. ... Cluster sampling is often more economical or more practical than stratifie...
may be considered in an effort to reduce the bias. It is conceivable that our method extends beyond the stratified sampling design, for example, the multi-stage sampling design considered in [7] and =-=[17]-=-, but this needs further research. APPENDIX Proof of Lemma 2.1. First we ...
