What is unsupervised classification in the context of cluster analysis?

• A.Grouping similar data points together without predefined labels
• B.Creating a scatter plot of data points
• C.Using a decision tree for data classification

Why are decision trees a useful technique for segmentation?

• A.Trees treat each split cell dependently based on earlier split decisions.
• B.Trees split the response into homogeneous groups, while maximizing the difference in the response of the groups.
