Cluster sampling is a sampling plan used when mutually homogeneous yet internally heterogeneous groupings are evident in a statistical population. It is often used in marketing research. In this sampling plan, the total population is divided into these groups (known as clusters) and a simple random sample of the groups is selected.

A company official wants to estimate the average cleaniness rating (from 1 to 7) of the bathrooms of these gas stations. A two-stage cluster sampling is desirable in this case due to travel costs. Cluster sampling is a technique that generates statistics about certain populations. It has a specific format required to obtain an appropriate sample, and though this sampling can help accurately gauge some information, it is not thought as accurate as simple random samples, where all groups of the same size have the same exact chance of being selected. Figure 1 shows an example of cluster sampling and figure 2 shows an example of systematic sampling. Secondary units of a primary unit of the cluster sampling are close together whereas secondary units of a primary unit of the systematic sampling separate from each other.

Cluster sampling procedure enables to obtain information from one or more areas. Demerits of cluster sampling. The following are the disadvantages of Cluster sampling: In a cluster sample, each cluster may be composed of units that is like one another. -- Created using PowToon -- Free sign up at http://www.powtoon.com/youtube/ -- Create animated videos and animated presentations for free.

A random sample of these groups is then selected to represent a specific population. It is a process which is usually used for market research when there is no feasible way to find information about a population or demographic as a whole.

popula on. Sampling: concerned with the selec on of a subset of a popula on (sample) to -clusters are selected as in the cluster sample, then sample.
For example, clusters like city blocks, school districts, age, sex, etc. Cluster sampling is the most efficient sampling technique and is most suitable when the individuals in the population inside the clusters do not have any diversity in them. In the cluster sampling method unlike stratified sampling, the elements of the population are selected collectively. Chapter 5 Cluster Sampling.

Objective: Describing how the cluster sampling statistical technique can be applied to health surveys. Methods: The article describes the most important aspects
to as cluster sampling. A random sample of clusters from the population is obtained and all members of the selected clusters are included in the resulting sample. After the selection of clusters, no further sampling takes place. Cluster sampling is often used to select participants for a trial—so called, cluster trials. Cluster Sampling . Problem 3.
