Questionnaires and Web Experiments

A questionnaire is a type of research instrument that has questions in a standardized format to capture responses from respondents. The responses to each question (item) in a structured survey can be aggregated and examined statistically. Questionnaires are employed in a variety of types of research, including market research as well as scholarly studies.

It is important to consider the intended people who will be taking part in your survey when designing your survey. The questions should be simple and clear, without the use of words that are difficult to comprehend for those who are not experts. It is also essential to keep the length of the survey short. Respondents dislike long surveys, and the longer a survey more lengthy, the lower its response rate will be.

Web experiments are the method of conducting online experiments using a browser-based interface, such as a site or mobile app. The advantages of this method include the possibility of creating interactive and personalized experiments, the ability to monitor user activities, and the possibility of using conditional branching that is based on previous answers provided by the participant.

The disadvantages of web-based research include the lack of a control group which can lead to unintentional confounding and poor generalization. Also, it is difficult to analyze the results of a web-based experiment due to its interactivity.

It is also important to pretest your questionnaire, at the very minimum, with a convenient sample before administering it in the field. This will allow you to discern ambiguity, unclear language or biases in questions and eliminate them prior to you distribute the questionnaire to your target population.
