Scientific glossaryData qualityOrigin: Yolia's safe educational catalogExact route: /biblioteca?ruta=glosario/calidad_dato FULL TOPICData quality Easy explanation It describes how reliable and truly useful a measurement or a statement is within a case's record. Poorly recorded or context-less data can lead to wrong conclusions even if the number itself seems correct. That's why Yolia asks where a piece of data comes from before using it. Medium explanation A number with no clear origin or sufficient context can be much less useful than it first appears. Yolia checks these factors before relying on a datum to build any interpretation or recommendation. A datum with a clear date and context is worth more than a loose one. Advanced explanation Assessment of validity, precision, provenance, completeness, consistency, timeliness, and applicability of a specific observation, which determines how much real weight it can carry within an interpretation of the case. Low-quality data limits any subsequent inference.
