Which statement best describes the What-If Tool's use in model evaluation?

• A. It lets users visualize outcomes in hypothetical scenarios
• B. It automatically fixes biased predictions
• C. It encrypts model parameters for security
• D. It manages data pipelines

Answer: (A)

The What-If Tool is used to explore model behavior by visualizing outcomes under hypothetical inputs. It lets you edit input features and immediately see how predictions change, enabling counterfactual thinking and scenario analysis. This makes it a powerful aid in model evaluation because you can assess robustness, fairness, and sensitivity across different conditions and inputs without retraining.

It doesn’t automatically fix biased predictions, nor does it encrypt model parameters or manage data pipelines. Those tasks involve bias mitigation, security features, and data engineering workflows, which fall outside its purpose.
