Sometimes while conducting research, you may come upon a piece of research already completed in a different study, but which answers what you want to say in your own writing. Be sure the data sets meet your criteria for your paper and that the research is not out of date. It is OK to use this research, as long as you cite the work properly. There are various citation guides, so be sure you know whether you are using, for example, MLA, APA, or CMS.
Find the author or organisation who conducted the original survey or questionnaire followed by a period. Always cite the last name then first name of authors and separate multiple authors with a comma.
Write the title of the survey or questionnaire in quotation marks, followed by a period inside the closed quotation. The title should be capitalised as it is found on the title page of the original document.
Write the word Questionnaire and a period after the title. This tells the reader what the medium is, if it was a survey, then type Survey.
Type the name of the journal or publication where the information was found followed by a period. If you found your information on an independent website, then skip this step as the website information will be included at the end of the citation.
Include the city where the original survey or questionnaire was conducted, or where the authors compiled the data, followed by a colon. It is only necessary to include the city and not the state.
Write the year the original questionnaire was conducted followed by a period. The year should be the year the questionnaire data was published if the years are different.
Type the website on which the information was originally printed, if available, followed by a period. If you did not use a website to gain this information, then do not include this section.
Make sure the questionnaire source you are using is the place it was originally published and not published second-hand from somewhere else (if it was published second-hand, check that researcher's works cited for the original document).
