"Heads Down" Data EntryData entry with no error detection occurring at the time of entry. Data entered in a heads down mode is often verified by re-keying the questionnaire and comparing the two-keyed copies of the same questionnaire. Data entered in a "heads-down" fashion may later be corrected in either a "batch" or an "interactive" data review process.

Heads up data entry requires subject-matter knowledge by the individuals entering the data. Data entry is slower, but data review/adjustment is reduced since simple inconsistencies in responses are found earlier in the survey process. This mode is very effective when the interviewer or respondent enter data during the interview (CAI).

Sequential or simultaneous imputation via cold-deck or hot-deck method may be applied. Source: UNECE Data Editing Group Hot-deckA correction base for which the elements are continuously updated during the data set check and correction. Typically edit-passing records from the current database are used in the correction database.
