Completion rate and response rate
Completion rate
Share of those who completed out of those who started. Shows how well the survey keeps respondents to the end.
Response rate
Share of those who responded out of those invited. Completion rate is usually higher: the denominator only includes those who already started.
How to improve completion rate
Shorten the survey, remove unnecessary questions, add a progress bar, avoid required open-ended questions at the start.
