1. Read for period interpretation. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for baseline clarity. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for context need. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.

Interpretation caution: Correlation is not evidence of causation.
