Challenges and Advantages of Questionnaires and Web Experiments

Questionnaires play an essential role in research. They help us gather data that can reveal the hidden truth about people. However, they do have their limitations.

Questions can be self-administered, with participants answering all questions themselves, or researcher-administered, where the research team interviews a sample of respondents by phone, in-person, or online. Self-administered questionnaires tend to have lower response rates than researcher-administered questionnaires, due in part to the impersonal nature of mailed paper surveys and automated telephone menu systems.

Web-based surveys offer a range of advantages, such as broader reach than traditional telephone or mail-based surveys and the ability to engage a global audience. However, they also come with problems, like the difficulty in reaching a representative sample of the population. They can also be subject to issues such as screen size as well as hardware platform, operating system and browser settings, which could influence the responses.

When creating a survey, it is essential to consider the research goals and objectives. When designing questions it’s crucial to know your target audience. For instance, you need to know whether they can comprehend and respond to the questions or do they have the time to fill out a lengthy questionnaire.

To ensure that the new questionnaires are working as intended, it’s important to test them in advance using qualitative methods such as focus groups, cognitive interviewing or pretesting. Additionally, questionnaires are susceptible to “question order effects” where the answers to questions from earlier ones can alter the answers to subsequent questions.
