Introduction to Evidence-Based Decision Making

This lesson introduces evidence-based decision making as a practical discipline: defining a decision, identifying the evidence needed, and separating signal from noise. Learners will see how data supports better choices when paired with business context, judgment, and clear criteria for success.

The focus is on foundations: why intuition alone is risky, what counts as useful evidence, how to frame decision questions, and how to avoid common mistakes such as confirmation bias and metric overload. More advanced analysis methods, dashboards, and experimentation techniques are saved for later lessons.
