Survey Response Rate
Response rate is the percentage of invited respondents who completed (or at least started) a survey.
Response rate is critical to survey validity — low response rates introduce nonresponse bias. Calculated as (Completed responses / Invited respondents) × 100. Channel matters: in-app micro-surveys average 27.5% (Refiner 2026), email 3-15%, SMS 3-15% click-through. Length matters: response rate drops ~40% from 1-question to 4-question micro-surveys.
