A questionnaire is a type of research instrument that has questions in a standardized format to gather responses from respondents. The responses to each question (item) on a well-structured survey can be gathered and assessed statistically. Questionnaires are commonly used in various types of research, including market research and scholarly research.
When designing your survey, it is essential to consider the people you’re aiming at. The questions should be straightforward and easy to comprehend, without technical terms or jargon which are difficult for novices. It is also essential to keep the duration of the survey brief. Respondents dislike long surveys, and the longer a survey is shorter, the lower the response rate will be.
Web experiments are an online research method that employs the browser as an interface, for example websites or mobile applications. The advantages of this approach include the ability to design interactive and personalized experiments, the ability to monitor user activities, and the ability to use conditional branching based on previous answers given by the participant.
Web experiments cannot be controlled, which can result in confusion or poor generalization. Due to the nature of interaction of web-based experiments, it may be difficult to analyze the results.
It is also essential to test the questionnaire even if you are using a convenient sample, prior to handing it out in the field. This will help you identify any ambiguity or unclear wording in the questions and eliminate them prior to administering the survey to your target audience.
