A questionnaire is a tool for research that has questions in the standard format that can be used to record the responses of respondents. Responses to the individual questions (items) on an organized questionnaire can be compiled into a scale or index for statistical analysis. Different types of research use questionnaires, including academic research and market research.
It is important to consider the intended target audience when designing it. The questions should be straightforward and understandable without using technical terms or jargon that are confusing for people who are not experts. It is also essential to keep the length of the survey to a minimum. The longer the survey the more unlikely respondents are to take part.
Web experiments are the method of conducting online research using a browser-based interface like a website or mobile app. This method offers many advantages, such as the possibility to create interactive and customized tests, the capability of monitoring user activity and conditional branching depending on the answers previously given by participants.
Web-based experiments are not controlled, and this could result in confusion or a poor generalization. Also, it can be difficult to evaluate the outcomes of a web-based study, due to its interactive nature.
Lastly, it is important to test your questionnaire at least using a convenience sample, prior to administering it in the field. This will enable you to detect ambiguity, unclear language or biases in questions, and eliminate them before administering the questionnaire to your target population.
