Flashcard Practice Certified Data Science Practitioner - CDSP Multiple Choice

Choose the Best Answer

Map north to 1, south to 2, east to 3, and west to 4 as a business ranking Replace region with the branch manager's employee ID Drop region before checking whether it improves validation and fairness metrics Use one-hot encoding so the model does not treat regions as ranked numbers
