What Are the Most Effective Data Quality Metrics to Measure Accuracy and Consistency?

Hey! Data quality metrics can definitely feel overwhelming, but once you break it down, it’s not so bad. For accuracy, I usually rely on error rates and outlier detection. For consistency, I look at how often data points align across different sources.

One tool I’d recommend is Apache Griffin. It’s open-source and great for defining and monitoring data quality metrics. Also, check out Dataiku if you’re into more visual workflows.

Hope this gives you a starting point!
