A questionnaire is a tool to conduct research. It contains questions in an established format to collect the responses of the respondents. Responses to the individual questions (items) on the questionnaire can be combined into a composite scale or index to allow statistical analysis. Different types of research use questionnaires, including market research and academic studies.

When you design your survey, it is important to consider the target audience. The questions should be straightforward and easy to understand, without using jargon or technical terms that are confusing for people who are not experts. The length of the survey should also be kept to a minimum. Respondents dislike long surveys, and the longer a survey is longer, the lower the response rate will be.

Web experiments are an online experimental method of research that utilizes a browser-based interface such as an application for mobile devices or a website. This approach has many advantages, including the ability to create interactive and personalised tests, the ability of tracking user activity, and conditional branching in accordance with the answers given previously by participants.

Web-based experiments are not controlled, which can result in confusion or a poor generalization. Also, it can be difficult to analyze the results of a web-based study, because of its interactive nature.

It is also important to practice the questionnaire, in the case of a convenience sample, prior to handing it out in the field. This will allow you to detect ambiguity, unclear language or biases in the questions and eliminate them prior to you distribute the questionnaire to your intended audience.
