What is The Dendrogram?

Create Your Dendrogram Now

1. What is A Dendrogram?

A dendrogram is a tree diagram that is used to represent and categorize hierarchical relationships among objects. The picture is an output from the illustration of hierarchical clustering. The name comprises clades (branches) that are further integrated into smaller branches. Individual elements are placed at the lower level, grouped according to the attributes, and placed at higher levels. The end of each chapter (also called leaf) is the data.

2. How to Read A Dendrogram?

A dendrogram can be interpreted by observing the height of any two objects that are joined together. For instance, we can look at the above diagram where E and F appear to be most similar. This can be depicted by the height of the links that connect them being the smallest. The next similarity can be seen in the objects A and B.

In some dendrograms, the height of the dendrogram depicts the order in which clusters are grouped. A more detailed dendrogram will indicate the distance between the clusters through heights. In such an instance, as represented below, the dendrogram shows the huge difference between clusters A and B versus C, D, E, and F.

A dendrogram illustrates and summarizes the distance matrix between the two objects. In most cases, there is a loss of information. For example, in the dendrogram mentioned above, it can be seen that C and D appear to be closer than C is to B. but if we look at the scatterplot, the story seems to be different. Hence, it is often said that a dendrogram is only considered adequate when the data persuades the ultrametric tree inequality, which appears to be implausible for the real-world data. The repercussion of the loss of information includes that dendrograms are the most precise at the bottom, depicting which objects are more similar.

This diagrammatic representation is constituted of a root node that gives birth to several nodes that are further connected by edges or branches. This shows the hierarchical relationship between objects that is relatively simple to understand.
