ANS:Below are the steps in making a decision tree
  1. Take the entire data set as input.
  2. Look for a split that maximizes the separation of the classes. A split is any test that divides the data into two sets.
  3. Apply the split to the input data (divide step).
  4. Re-apply steps one and two to the divided data.
  5. Stop when you meet any stopping criteria.
