PRESS RELEASE (May 10, 2016):
Understanding and Interpreting Opinion Polls:
New International Online Course for Journalists 


A Media Guide to Survey Research

The World Association for Public Opinion Research (WAPOR) is dedicated to developing the science of survey research and promoting its appropriate use around the world. It specifically seeks to “promote international cooperation and exchange” with journalists and inform them about “the appropriate forms of publishing poll results.”[1] To further these goals, WAPOR here provides information to journalists on learning about survey research and about what facts they should know when using surveys in a news story.
Learning about Survey Research

Just as journalists who cover politics need to be familiar with the political system and reporters covering legal cases need to be well-versed in judicial procedures, journalists using surveys need at least a basic grounding in survey research. As Katherine Wallman, president of the American Statistical Association (ASA) has noted, “statistical literacy” is required to report stories using surveys and other statistical data (Wallman, Katherine K., “Enhancing Statistical Literacy: Enriching Our Society,” Journal of the American Statistical Association, 88 (March, 1993), 1-8).


the best way for a journalist to gain competency about surveys is to complete an advanced degree in statistics or in quantitative social science. For a list of some graduate programs specializing in survey research see (http://www.aapor.org). Of course this possibility is not practical for many journalists.


a number of organizations offer short courses ranging from a few hours to a few weeks in survey methods. These include courses at:


there are on-line courses and webinars, some especially designed for journalists:


one can attend the general sessions of the annual conferences of the leading survey-research associations:

  • The World Association for Public Opinion Research (held in a three year rotation with Europe, North America and elsewhere) (http://wapor.org)
  • The ESOMAR (the World Association of Research Professionals) (www.esomar.org/)
  • The various national, survey-research associations such as those listed by ESOMAR (www.esomar.org/)
  • In addition, WAPOR frequently holds regional conferences around the world (http://wapor.org/seminars-events/)


there are a number of publications specially designed to inform journalists about surveys:

  • Friend, Cecilia and Challenger, Don., Contemporary Editing. 3rd edition. New York: Routledge, 2013.
  • Gawiser, Seldon R. and Witt, G. Evans, A Journalist’s Guide to Public Opinion Polls. Westport, CT: Praeger, 1994

there are various professional journals that can be consulted for the latest developments in survey research. These include the top two professional journals, WAPOR’s International Journal of Public Opinion Research and AAPOR’s Public Opinion Quarterly. Other important journals include the Field Methods, International Journal of Market Research, the Journal of Marketing Research, the Journal of Official Statistics, the Polling Report, Research World, Survey Methodology, and Survey Research Methods.

The Needed Facts about Surveys

Whenever using a survey in a story, journalists need to obtain basic methodological information on the data. The WAPOR Code of Professional Ethics and Practices (http://www.unl.edu/wapor/ethics.html) lists essential facts that should be included in all reports on surveys and therefore known about a survey that is used in a news story. In abbreviated form they are:

1. who commissioned the survey
2. who conducted the survey
3. the purpose of the survey
4. the universe the survey covers
5. sampling method and procedures
6. non-response rate
7. sample size (number of cases)
8. weighting procedures (if used)
9. data collection method
10. when data collected
11. results
12. characteristics of interviewers and coders and their training
13. copy of questionnaire
14. results for sub-samples vs. whole sample
15. precision of findings and sampling error when applicable
16. standard, scientific use of technical terms

Moreover, there is a high degree of agreement amongst survey-research organizations about what elements of surveys are crucial to report. See the similar, but not identical, disclosure lists of AAPOR, CASRO, and NCPP.
