Cluster sampling is a sampling technique used when "natural" groupings are evident in a statistical population. It is often used in marketing research. In this technique the total population is divided into these groups (or clusters) and a sample of the groups is selected. Then the...

a digital raster map called `a model forest' was generated on the basis of a Landsat Thematic Mapper (TM) satellite image and field data plots to describe spatial variation of the forest volume.The model forest was a map representing stem volumes in order to compare different sampling techniqu...
7 Cluster Sampling vs Stratified Sampling 8 Conclusion What is Cluster Sampling? 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 rando...
a subgroup that mirrors the diversity of the whole population while the set of clusters are similar to each other. Typically, researchers use this approach when studying large, geographically dispersed populations because it is a cost-controlling measure. This technique is aprobability sampling method...
A cluster sampling technique was used to select representative samples of the caregivers of young children in Karachi in general and of such caregivers in three of the six “high-risk” districts of the city where polio cases were detected in 2011. 使用集群抽样方法选择卡拉奇的幼儿照顾者的代表...
can be done using this sampling technique. LEARN MORE: Population vs Sample In this blog, we will be discussing Cluster Sampling vs Stratified Sampling. Factors for Comparison Cluster Sampling Stratified Sampling Definition Members of this sample are chosen from naturally divided groups called ...
This sampling technique is cheap, quick and easy. Instead ofsamplingan entire country when using simple random sampling, the researcher can allocate his limited resources to the few randomly selected clusters or areas when using cluster samples. ...

It is a type of probability sampling technique that studies large populations, especially one which is spread across a large geographical area. For obtaining a cluster sample, a particular number of clusters are selected randomly out of all the clusters present. After that, all the items covered...
