Best Practices 4 and 5 for Validating Data Sets
- Plan for “other” data responses.
Lists of answers to single-answer questions should include all possible responses. To encompass all the possibilities, include an “other,” category as answer and create a text box to capture the information.
- Plan for “prefer not to answer”
Leave a place for the interviewer to record “did not choose to answer” or “does not know.” This will avoid null data.
