What is the difference between complete and partial responses?
Partial Response: If the respondent clicks Next on at least one survey page, but doesn't click Done (or Submit) on the last page of the survey, it is considered a partial response.
Complete Response: If the respondent clicks Done (or Submit) on the last page of the survey, it is considered a complete response. However, it is possible for the respondents to skip questions without answering if there are questions that are not mandatory.
