More about Data Clustering

 
In two-way clustering, data is clustered by using its properties and is represented in a matrix.
 

Example of Data Clustering

 
The ages of 6 people participating in a swimming competition are 39, 34, 35, 34, 33, and 27. In this data, the cluster of ages 34, 35, 34, and 33 are close to the age 34.
 

Solved Example on Data Clustering

 

Identify the cluster in the given data set around the number 75.
56, 61, 71, 75, 77, 74, 76, 75, 75, and 60

 

Choices:

 
A. 75, 77, 74, 76, 75, and 75
B. 71, 61, and 60
C. 60 and 56
D. 77 and 56

 
Correct Answer: A

 
Solution:
 
 
Step 1: The numbers which are close around a particular number in a given set of data are called cluster.

 
Step 2:  In the data set, the numbers 77, 74, and 76 are close around the number 75.

 
Step 3: So, 75, 77, 74, 76, 75, and 75 from the cluster of the number 75.
