Questionnaires and web experiments allow research workers to reach a much wider readership than traditional paper forms, mobile phone or face-to-face interviews and can be conducted by a fraction of the cost. This makes them a fashionable tool for the purpose of market research and customer surveys as well as mental health studies. However , despite their various advantages they come with some negatives which can challenge the quality of the results.

One major issue is that there is less control over data capture than with a paper customer survey. With a Web experiment the participant can view stimuli on their own personal device and could also adjust settings such as screen size, browser, internet connection and perhaps the arrears font. This simply means that every respondent experiences a discreetly different set of questions and this can impact how they get suggestions.

Another problem is set of questions taking tiredness which can bring about respondents abandoning the survey. The way to prevent this is to make the questionnaire because short as is feasible and only find out that are highly relevant to your research. You can also try to randomize the order of the questions and pretest the questionnaire just before performing this to ensure that all the questions are crystal clear and understandable.

Finally, you will need to keep in mind that World wide web experiments derive from voluntary involvement so they can are more susceptible to motivational confounding than laboratory trials. To counter this, you can use a web based marketplace including SONA systems (often employed for undergraduate examining at universities), MTurk or Productive to sponsor participants.
