Correct Answer Explanation
Errors in Data Acquisition arise from the recording of incorrect responses. These are a type of non-sampling error.
Key Points:
- Example: Recording 13 instead of 31 (transposition error by enumerator or respondent).
- These errors can occur due to carelessness of students/enumerators, differences in measuring instruments, or misinterpretation of questions.
- Example: Different students measuring the length of a table may get different values due to different measuring tapes or carelessness.
- Also occurs when data like prices varies widely (shop to shop, market to market, quality to quality) — only average prices can be recorded.
