Correct answer & explanation
✓
Validity
Validity refers to whether data values conform to defined rules or constraints.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Completeness
Why it's wrong here
Completeness measures whether required values are absent or null, not whether present values sit inside a permitted domain or range. It is tempting because missing fields and out-of-range entries both surface as data quality defects, but validity is the dimension that checks conformance to a defined set of allowed values or bounds.
- ✗
Consistency
Why it's wrong here
Consistency concerns whether the same value is represented identically across systems and records, so it addresses conflicting duplicates rather than whether a value sits inside a permitted domain. It is tempting because inconsistent data often looks invalid, but validity is the dimension that checks domain and range conformance.
- ✓
Validity
Why this is correct
Validity checks that values conform to a defined domain, format or acceptable range, directly matching the stem's requirement. Unlike accuracy, which concerns correspondence to real-world truth, or consistency, which concerns agreement across sources, validity enforces permitted value sets and boundaries, so out-of-range or malformed entries fail the check.
- ✗
Accuracy
Why it's wrong here
Accuracy concerns whether a value correctly reflects the real-world fact it describes, so a plausible but wrong entry inside the permitted range still fails accuracy, not domain conformance. It is tempting because inaccurate data is often out of range, but validity is the dimension that tests values against a defined domain.
