Definition: Observation errors

Category: OECD - Business tendency surveys

Observation errors are components of non-sampling error and are generated during the data collection process. They may occur because the question is wrongly worded or misleading, because the interviewer makes an error whilst asking the question or because the interviewer records incorrectly the answer given by the respondent.
