A questionnaire is a type of research instrument that asks questions in a standardized format to gather responses from respondents. Responses to individual questions (items) on an organized questionnaire can be compiled into a scale or index to allow statistical analysis. Questionnaires are commonly used in various kinds of research, including market research and scholarly studies.
When designing your survey it is important to think about the target audience. The questions should be simple and understandable, without jargon or technical terms which are difficult for novices. It is also essential to keep the length of the survey to a minimum. Respondents do not like long surveys and the longer a survey, the lower the response rate will be.
Web experiments are a method of conducting online experiments using a browser-based interface, like a website or mobile application. The advantages of this method include the possibility of creating personal and interactive experiments, the capability to track user activity, and the ability to use conditional branching based on previous answers provided by the participant.
The disadvantages of web-based experiments include the absence of a control group which could lead to unintentional confusion and poor generalization. Also, it is difficult to evaluate the outcomes of a web-based study, due to its interactive nature.
It is also necessary to practice the questionnaire, even if you are using a convenient sampling, prior to distribution in the field. This will help you discern ambiguity, unclear language or biases in questions, and eliminate them before conducting the survey to your intended population.
