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.
Response rate may refer to: Response rate (medicine) – the percentage of patients whose cancer shrinks or disappears after treatment Response rate (survey) – the percentage of persons asked to answer a survey who actually answer
In behaviorism, rate of response is a ratio between two measurements with different units. Rate of responding is the number of responses per minute, or some other time unit. It is usually written as R. Its first major exponent was B.F. Skinner (1939). It is used in the Matching Law. R = # of Responses/Unit of time = B/t
For trials where the response rate is the primary endpoint it is strongly recommended that all responses be reviewed by an expert(s) independent of the study at the study's completion. Simultaneous review of the patients’ files and radiological images is the best approach.
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]
Survey methodology is "the study of survey methods". [1] As a field of applied statistics concentrating on human-research surveys, survey methodology studies the sampling of individual units from a population and associated techniques of survey data collection, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys.
The response rate is the percentage of patients on whom a therapy has some defined effect; for example, the cancer shrinks or disappears after treatment. [ 9 ] When used as a clinical endpoint for trials of cancer treatments, this is often called the objective response rate (ORR).
A common assumption is that response rates are linked to non-response bias, with lower response rates incurring a greater likelihood for results to be influenced by non-response bias. Academic research has disputed substantial linkages between response rate and non-response bias. A meta-analysis of 30 methodological studies on non-response bias ...
