Cluster Sampling. Cluster sampling. For instance, it can be necessary to cluster at the state or city level, units that may be small and fixed in number. Memories are naturally clustered into related groupings during recall from long-term memory.So it makes sense that when you are trying to memorize information, putting similar items into the … Instead of sampling individuals from each subgroup, you randomly select entire subgroups. Cluster sampling is a probability sampling technique in which all population elements are categorized into mutually exclusive and exhaustive groups called clusters. Cluster sampling requires multiple research points for it to reduce the sampling errors that the research produces. A target group is usually too large to study in its entirety, so sampling methods are used to choose a representative sample from the target group. Cluster sampling occurs when researchers randomly sample people within groups or clusters the people already belong to. Start studying Psychology - sampling methods. Since cluster sampling selects only certain groups from the entire population, the method requires fewer resources for the sampling process. In this method, the probability of selecting an element in any given cluster varies inversely with the size of the cluster. Although cluster sampling and stratified sampling bear some superficial similarities, they are substantially different. There is also a higher risk of obtaining one-sided data through this process if fewer examples are taken from each cluster. Clusters are selected for sampling, and all or some elements from selected clusters comprise the sample. Updated February 09, 2019 Cluster sampling may be used when it is either impossible or impractical to compile an exhaustive list of the elements that make up the target population. Cluster sampling methods can lead to significant bias when working with a small number of clusters. The advantages include: 1. Pros and Cons: External validity: The random nature of selecting clusters allows researchers to generalize from the sample to the entire population being studied. Advantages of Cluster Sampling. A population is an entire group with specified characteristics. 4. Ashley Crossman. Requires fewer resources. The cluster method comes with a number of advantages over simple random sampling and stratified sampling. Cluster sampling also involves dividing the population into subgroups, but each subgroup should have similar characteristics to the whole sample. Clustering involves organizing information in memory into related groups. Without high levels of research, the potential for data overlaps increases. Cluster sampling is the sampling method where different groups within a population are used as a sample. Probability-proportional-to-size sampling is a type of multistage cluster sampling.

The target group/population is the desired population subgroup to be studied, and therefore want research findings to generalise to.
