Answer to Question 1

A decision tree is a hierarchical arrangement of criteria that predicts a classification or
value. Decision tree analysis is an unsupervised data mining technique. An analyst sets up a
computer program and provides the data to analyze, and the decision tree program produces the
tree. The basic idea of a decision tree is to select attributes that are most useful for classifying
entities on some criterion.
The user should input data about different attributes into the decision tree program. The program
then analyzes all of the attributes and selects an attribute that creates the most disparate groups.
The logic is that the more different the groups, the better the classification will be. A decision
tree program creates groups that are as pure as possible. A common business application of
decision trees is to classify loans by likelihood of default.

Answer to Question 2

TRUE
