Certified in Data Science (CDS) Most CDS candidates underestimate the statistical rigor required for real-world model validation. They ace the Python syntax questions but falter when asked to identify when correlation masquerades as causation or when a model’s high accuracy hides severe class imbalance problems. Understanding how to detect overfitting through cross-validation techniques and recognizing when dimensionality reduction sacrifices interpretability separates passing scores from credential holders who can actually deploy ML responsibly.
