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.
However, lower costs are not so straightforward in practice, as they are strongly interconnected to errors. Because response rate comparisons to other survey modes are usually not favourable for online surveys, efforts to achieve a higher response rate (e.g., with traditional solicitation methods) may substantially increase costs. [1]
The P program can be used for studies with dichotomous, continuous, or survival response measures. The user specifies the alternative hypothesis in terms of differing response rates, means, survival times, relative risks, or odds ratios. Matched or independent study designs may be used.
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.
For instance in a telephone survey of the US and you normally get 45% response rate (45% of people called complete the survey questions) but you run a poll in the middle of the superbowl or 2am in the morning and the response rate drops to 10%, then the sample is skewed - thos e 10% who complete are different from the other 90% of the telephone ...
Survey methodology (2010 2nd ed. [2004]) ISBN 0-471-48348-6. The other books focus on the statistical theory of survey sampling and require some knowledge of basic statistics, as discussed in the following textbooks: David S. Moore and George P. McCabe (February 2005). "Introduction to the practice of statistics" (5th edition). W.H. Freeman ...
These modifications included changing the 1-10 rating scale to be from 1-9, which 0 used as "not applicable". This also simplified future data entry for the questionnaire since a maximum rating would no longer require two keystrokes (as it would have in "10"). This in turn would reduce response bias from subjects. [2]
In practice, the sample size used in a study is usually determined based on the cost, time, or convenience of collecting the data, and the need for it to offer sufficient statistical power. In complex studies, different sample sizes may be allocated, such as in stratified surveys or experimental designs with multiple treatment groups.
