The effects of data entry error: an analysis of partial verification.
Modern data entry technology has greatly reduced entry errors by building quality control mechanisms such as cross-field and range edits directly into data entry programs. In many application areas the increased accuracy of modern data entry techniques has made 100% verification unnecessary to assure high standards of data quality. Verification of randomly selected forms combined with 100% verification of critical fields provides a cost efficient alternative to 100% verification of all fields. This paper analyzes the effects of data entry error on study findings and provides a basis for designing a partial verification scheme for achieving quality control goals in a cost efficient manner.
