Create Your Own Decision Tree

Create Your Own Decision Tree

Use your selected training data to create a decision tree. Your decision tree should:

• Use 'yes/no' questions only: Only ask questions that can be answered using your training data.

• Contain Ending Points: Continue asking questions at each branch of the tree until you come up with only one answer remaining (all your branches end with 'leaves').
• Identify key nodes, including the root and leaves.

You may create your decision tree in any format you choose, including online chart creation tools, handwritten drawings, and post its or notecards photographed for submission.
