Transcribed image text: In the lab, a classification tree was applied to the Carseats data set af- ter converting Sales into a qualitative response variable. Some features may not work without JavaScript. Since some of those datasets have become a standard or benchmark, many machine learning libraries have created functions to help retrieve them. A decision tree is a flowchart-like tree structure where an internal node represents a feature (or attribute), the branch represents a decision rule, and each leaf node represents the outcome.
