DefinitionA questionnaire survey (アンケート) hands out a preset set of question items to many people and tallies the returned answers to see overall trends.
ExplanationBecause everyone gets the same questions in the same format, the answers are easy to turn into counts or percentages and compare. It can be run on paper or through a web form, so many people can be covered in a short time. On the other hand, it rarely draws out answers to questions you did not prepare, or the reasons behind an answer.
Memory hookThe Japanese word comes from the French enquête (inquiry). In English it is called a questionnaire or a survey.
