2. Read for ambiguous wording. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for description improvement. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
