Data Quality Dimensions

5 to work through

A supplier table has 12% of rows with a blank tax identifier and 3% where the identifier is present but does not match the registry. Both are called data quality issues in the same report. Why does separating them change who is asked to fix them?

A nightly freshness check alerts when a table's daily row count deviates more than 20% from the previous day. Volume follows a weekly pattern: weekends run about 40% below weekdays. Roughly how many alerts a month does this produce before anything is actually wrong, and what should replace it?

A team wants to measure data quality. Which dimensions matter, and which tests actually catch problems?

You are setting data quality thresholds for a dataset with five consuming teams. How do you decide the numbers?

A marketplace's seller metrics look wrong but every pipeline succeeded and every test passed. How do you diagnose it?
