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.
A good sample selection is key as it allows one to generalize the findings from the sample to the population, which is the whole purpose of survey research. In addition to this, it is important to ensure that survey questions are not biased such as using suggestive words. This prevents inaccurate results in a survey.
In statistics, survey sampling describes the process of selecting a sample of elements from a target population to conduct a survey. The term "survey" may refer to many different types or techniques of observation. In survey sampling it most often involves a questionnaire used to measure the characteristics and/or attitudes of people.
Therefore, non-response bias may make the measured value for the workload too low, too high, or, if the effects of the above biases happen to offset each other, "right for the wrong reasons." For a simple example of this effect, consider a survey that includes, "Agree or disagree: I have enough time in my day to complete a survey."
In survey research, the design effect is a number that shows how well a sample of people may represent a larger group of people for a specific measure of interest (such as the mean). This is important when the sample comes from a sampling method that is different than just picking people using a simple random sample .
The DHS Program works to provide survey data for program managers, health care providers, policymakers, country leaders, researchers, members of the media, and others who can act to improve public health. The DHS Program distributes unrestricted survey data files for legitimate academic research at no cost. [citation needed]

In Northern Ireland, the GP patient survey ran from 2008/09 to 2010/11. [2] The results of the survey are published by Ipsos on behalf of NHS England on the GP Patient Survey publication website. [3] Results are available for individual practices and their results are compared to the national average and the local Clinical Commissioning Group.
