Which statistical method is used to adjust outcome comparisons between groups that differ in baseline characteristics, commonly applied in population health research?
Answer: Risk adjustment / case-mix adjustment
Risk adjustment (case-mix adjustment) accounts for differences in patient demographics and severity to enable fair comparisons.
A health informatician is evaluating an analytics dashboard and notices that the same metric shows different values in two reports. The most likely cause is:

What does 'data governance' ensure in a population health analytics program?
Answer: Consistent data quality, ownership, and access policies across the organization
Data governance establishes policies, roles, and standards to ensure data quality, integrity, and appropriate access across the organization.
