Accuracy: Data should be correct and free from errors. Reliable data accurately represents the real-world phenomenon it is intended to measure.
Consistency: Data should be uniform and coherent across different systems or datasets. Inconsistent data can lead to confusion and incorrect conclusions.
Completeness: Data should be comprehensive and contain all necessary information. Incomplete data can lead to misinformed decisions.
Timeliness: Data should be up-to-date and relevant to the current context. Outdated data can be misleading and less useful.
Source Credibility: Data should come from reputable and verified sources. Reliable sources ensure the data's validity and accuracy.
