CLUSTER ANALYSES Meaning and
Definition
-
Cluster analysis is a statistical data analysis technique used to identify groups or clusters within a dataset. It involves the organization and classification of data into groups or clusters, based on similarity between the individual data points.
In cluster analysis, data points that are similar to each other are assigned to the same cluster, while data points that are dissimilar are assigned to different clusters. The similarity or dissimilarity between data points is measured based on various criteria such as distance, density, or connectivity. The main objective of cluster analysis is to identify and understand the patterns, relationships, or structures within the dataset.
Cluster analysis can be applied to various types of data, including numerical, categorical, or mixed data. It is commonly used in fields such as marketing, biology, social sciences, and pattern recognition. It enables researchers and analysts to uncover hidden information or patterns, identify natural groupings or classifications of data, and gain insights for making informed decisions.
There are various algorithms and methods available for performing cluster analysis, such as K-means clustering, hierarchical clustering, and density-based clustering. These algorithms utilize different approaches to identify the optimal clusters within the dataset. The choice of algorithm depends on the nature of the data, the objectives of the analysis, and the specific requirements of the problem at hand.
Cluster analysis provides a valuable tool for organizing and understanding complex datasets, enabling researchers and analysts to uncover meaningful patterns and insights that may not be apparent through simple data examination.

Etymology of CLUSTER ANALYSES
The word "cluster" in the field of data analysis and statistics comes from the Old English word "clyster", which meant "group" or "swarm". It derived from the Old High German word "kluostar" which meant "flock of birds" or "cluster of grapes".
The word "analysis" comes from Latin, derived from the Greek word "analyein", which meant "to untie", "to loosen", or "to break up". It was used in the context of separating or breaking down a complex problem into simpler components for examination.
When combined, "cluster analyses" refers to the method of analyzing data by grouping similar objects or individuals together into clusters based on shared characteristics, and then studying the characteristics and relationships within each cluster.
