Correct answer & explanation
Accuracy: Data correctly reflects real-world values
The correct matches are: Accuracy - data correctly reflects real-world values; Completeness - all required data is present; Consistency - data values are the same across systems; Timeliness - data is available when needed. Common confusions include mixing timeliness with accuracy and consistency with completeness.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Accuracy: Data correctly reflects real-world values
Why this is correct
Accuracy refers to the degree to which data correctly represents the real-world entity or event it is meant to represent.
Completeness: All required data is present
Why this is correct
Completeness measures whether all necessary data elements are available and no critical information is missing.
Consistency: Data values are the same across different systems or sources
Why this is correct
Consistency ensures that data does not contain contradictions and is uniform when compared across datasets.
Timeliness: Data is available when needed
Why this is correct
Timeliness refers to the availability of data at the time required for decision-making or processing.
Accuracy: Data is available when needed
Why it's wrong here
Incorrect — this describes Timeliness, not Accuracy.
Completeness: Data values are the same across different systems
Why it's wrong here
Incorrect — this describes Consistency, not Completeness.
