A questionnaire is a tool for research that contains questions that are in a standard format to gather the responses of the respondents. Responses to the individual questions (items) on an organized questionnaire can be aggregated into a composite scale or index to allow statistical analysis. Questionnaires are employed in a variety of types of research, including market research and scholarly research.
When designing your survey it is essential to consider the target audience. Questions should be clear and understandable without the use of jargon that is difficult for non-experts to interpret. The length of the survey must be kept short. Respondents dislike long surveys, and the longer a survey is, the lower the response rate will be.
Web experiments are the method of conducting online experiments with a browser-based user interface, such as a site or mobile app. This approach has many advantages, including the ability to create interactive and customized tests, the ability of monitoring user activity and conditional branching depending on the previous answers given by participants.
The disadvantages of web-based experiments include the lack of a control group which could lead to unintentional confusion and poor generalization. Also, it may be difficult to assess the results of a Web-based experiment due to its interactivity.
It is also essential to practice the questionnaire, in the case of a convenience sampling, before distributing it on the field. This will help you spot any ambiguity or unclear wording in the questions and eliminate them prior to giving the survey to your desired audience.
