What Is a Decision Tree?
Progress
1 / 8
Understand decision trees as an intuitive ML model.
Read one card at a time. Focus on the main idea first, then look at the visual on the right to help it stick.
A decision tree uses a sequence of yes or no questions.
It is structured like a flowchart with branches.
It can be used for classification or regression.
It is often easier to explain than many other models.
This makes it appealing for beginner-friendly interpretability.
Remember
Decision trees are appealing because their reasoning can often be visualized directly.
