The cluster is a group of subjects (consumers) or objects (products, brands) that are united by various characteristics and grouped according to certain criteria.
The cluster is constructed through statistical analyses that allow the pairing of individuals or objects with identical characteristics.
This technique is defined as cluster analysis, and is used in the field of marketing for market segmentation purposes.
Cluster Analysis
Cluster analysis is used as a specific sampling technique, instead of random sampling.
In cluster sampling, units of a statistical sample that have been identified with a number of homogeneous characteristics are grouped together, and then they are subsequently grouped into clusters.
This sampling technique offers several advantages, namely:
- Containment of research costs;
- Limited number of clusters.
Therefore, thanks to the cluster technique, it is easier to find subjects or objects with homogeneous characteristics.
Computer cluster
Going into more detail regarding computer science, a computer cluster consists of a series of interconnected machines that work in parallel.
