A U.S. National Agricultural Statistics Service statistician explains response rate data at a 2017 briefing to clarify the context of crop production data. In survey research, response rate, also known as completion rate or return rate, is the number of people who answered the survey divided by the number of people in the sample.
The term "design effect" was coined by Leslie Kish in his 1965 book "Survey Sampling." [1]: 88, 258 In it, Kish proposed the general definition for the design effect, [a] as well as formulas for the design effect of cluster sampling (with intraclass correlation); [1]: 162 and the famous design effect formula for unequal probability sampling.
Data often are missing in research in economics, sociology, and political science because governments or private entities choose not to, or fail to, report critical statistics, [1] or because the information is not available. Sometimes missing values are caused by the researcher—for example, when data collection is done improperly or mistakes ...
Academic research has disputed substantial linkages between response rate and non-response bias. A meta-analysis of 30 methodological studies on non-response bias by Robert M. Groves found that the coefficient of determination for variance in non-response bias by response rate was only 0.11, making it a weak predictor of non-response bias ...

Response bias is a general term for a wide range of tendencies for participants to respond inaccurately or falsely to questions. These biases are prevalent in research involving participant self-report, such as structured interviews or surveys. [1] Response biases can have a large impact on the validity of questionnaires or surveys. [1] [2]
Each response point has an accompanying verbal anchor (e.g., “strongly agree”) ascending from left to right. Verbal anchors should be balanced to reflect equal intervals between response-points. Collectively, a set of response-points and accompanying verbal anchors are referred to as a rating scale.
