A Bengaluru analyst builds a dashboard of customer records where 40 of 500 entries have a missing PIN code. Which data-quality measure is correctly computed for the PIN code field?
Completeness of the PIN code field is 92 percent, because 460 of the 500 records contain a value. The 8 percent figure is the proportion missing, which is the complement of completeness, not the completeness measure itself.
- ACompleteness 92%Correct
- BCompleteness 8%
- CCompleteness 40%
- DCompleteness 88%
Explanation
Complete entries = 500 - 40 = 460. Completeness = 460/500 = 92%. The 8% figure is the missing proportion, not completeness.
