## FAQs on Complete & Incomplete Linkage Video Lecture - Biology Class 12 - NEET

Ans. Complete linkage and incomplete linkage are two different methods for clustering analysis. In complete linkage, the distance between two clusters is determined by the maximum distance between any two points in the two clusters. On the other hand, incomplete linkage calculates the distance between two clusters based on the minimum distance between any two points in the two clusters. Therefore, the main difference lies in how the distance between clusters is calculated.
 2. How is complete linkage used in clustering analysis?
Ans. Complete linkage is a popular method in clustering analysis. It is used to measure the distance between two clusters by considering the maximum distance between any two points in the clusters. This method tends to produce compact and well-separated clusters. It is particularly useful when dealing with data that contains outliers or when the clusters have different shapes and sizes.
 3. What are the advantages of using incomplete linkage in clustering analysis?
Ans. Incomplete linkage has several advantages in clustering analysis. Firstly, it is less sensitive to outliers compared to other methods. This means that outliers have less influence on the overall clustering result. Secondly, incomplete linkage can handle clusters with different shapes and sizes effectively. It allows for more flexibility in defining the boundaries of clusters. Lastly, incomplete linkage tends to produce more balanced clusters, making it suitable for datasets with varying densities.
 4. Can complete linkage and incomplete linkage be used together in clustering analysis?
Ans. Yes, complete linkage and incomplete linkage can be used together in clustering analysis. This approach is known as hybrid linkage. By combining the strengths of both methods, hybrid linkage aims to overcome their individual limitations. It provides a more comprehensive analysis of the data and can yield more accurate and meaningful clusters. However, implementing hybrid linkage requires careful consideration of the specific dataset and research objectives.
 5. How can I determine which linkage method is appropriate for my clustering analysis?
Ans. The choice between complete linkage and incomplete linkage depends on the characteristics of your dataset and the objectives of your clustering analysis. If your data contains outliers or the clusters have different shapes and sizes, complete linkage may be more suitable. On the other hand, if you want to be less affected by outliers and have more flexibility in defining cluster boundaries, incomplete linkage is a better choice. It is recommended to experiment with both methods and evaluate the clustering results to determine the most appropriate linkage method for your specific case.
