Match List - I with List - II :
| List - I | List - II |
|---|---|
| I. Errors associated with age | 1. Post enumeration check |
| II. Direct Method of data evaluation and error detection | 2. Ambiguity in the questionnaire / schedule |
| III. External consistency check | 3. Balancing equation |
| IV. Content error | 4. Coverage error |
Codes :
I II III IV
Answer: A
The key gives the codes 4, 2, 3, 1 (option A) for I to IV. The pairing of the external consistency check with the balancing equation (III-3) is the one that is easy to confirm, since the balancing equation compares census counts with births, deaths and migration over the period. The key also pairs content error with the post enumeration check (IV-1), as a re-survey tests the correctness of the recorded answers, and errors associated with age with coverage error (I-4). The other options pair the balancing equation or the check differently from the key, so they are rejected. The key's second pair is taken as printed.
