[19] [20] Furthermore, the results of survey research can inform the public health domain and help conduct health awareness campaigns in vulnerable populations [15] and guide healthcare policy-makers. This is especially true when survey research deals with a wide spread disease that constitutes a nationwide or global health challenge.
The type of site survey and the best practices required depend on the nature of the project. [1] Examples of projects requiring a preliminary site survey include urban construction, [ 2 ] specialized construction (such as the location for a telescope) [ 3 ] and wireless network design.

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]
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.
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 National Health and Nutrition Examination Survey (NHANES) is a survey research program conducted by the National Center for Health Statistics (NCHS) to assess the health and nutritional status of adults and children in the United States, and to track changes over time. [1] The survey combines interviews, physical examinations and laboratory ...
A frame may also provide additional 'auxiliary information' about its elements; when this information is related to variables or groups of interest, it may be used to improve survey design. While not necessary for simple sampling, a sampling frame used for more advanced sample techniques, such as stratified sampling , may contain additional ...
