A questionnaire is a tool for research that has questions that are in a standard format to capture the responses of the respondents. Responses to specific questions (items) on the questionnaire can be compiled into a scale or index for statistical analysis. Questionnaires are employed in a variety of kinds of research, including market research and scholarly research.
It is important to consider the intended target audience when designing your survey. The questions should be straightforward and understandable, without technical terms or jargon that are confusing for people who are not experts. It is also essential to keep the length of the survey short. Respondents do not like long surveys and the longer a survey, the lower the response rate will be.
Web experiments are an online experimental method of research that utilizes web-based interfaces, such as an application for mobile devices or a website. This method has numerous advantages, such as the possibility of creating interactive and personalised tests, the ability to monitor user activity and conditional branching depending on the answers previously given by participants.
The drawbacks of web-based experiments include the absence of a control group which can lead to unintentional confounding and poor generalization. Due to the interactive nature of web experiments, it can be difficult to evaluate the results.
It is also crucial to pretest the questionnaire, in the case of a convenience sample, prior to distributing it on the field. This will allow you to discern ambiguity, unclear language, or biases in the questions and eliminate them prior to giving the questionnaire to your targeted population.
