Cluster Sampling Example For example, imagine we are studying rural communities in a state. Simple random sampling requires us to travel to all these communities just to get a few subjects from each place, which could be cost and time prohibitive. However, we can divide rural communities into ...

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...

The important thing to remember about this sampling technique is to give all the clusters equal chances of being selected. Types of Cluster Sample One-Stage Cluster Sample Recall the example given above; one-stage cluster sample occurs when the researcher includes all the high school students from...
Cluster sampling: Cluster sampling refers to a probability sampling technique involving random selection of groups instead of individuals from a population. It is a multistage sampling in which natural groups (clusters) are sampled initially, with the . . . ...
This method combines the sampling technique with PAM; however, it is not limited to a single sample at a specific time. CLARANS represents a sample with some randomness in each phase of the search, whereas CLARA has a fixed sample at every step of the search. The clustering approach can ...
The technique seeks to produce clusters that are internally as homogeneous as possible in conditional distributions P(cℓ | t∈ C) {cℓ being a class and t being an example) of the auxiliary attribute, i.e., belong to a single class. Similarly, the information bottleneck algorithm is ...
For example, clustering may help an insurance company identify groups of motor insurance policyholders with a high average claim cost. The purpose behind clustering depends on how a company intends to use it, which is largely informed by the industry, the business unit, and what the company is...

In what situations would sampling work best for estimating population size, in what situations would mark and recapture work best and why?
