Questionnaires and web experiments allow analysts to reach a much wider customers than traditional paper questionnaires, mobile phone or face-to-face interviews and is conducted in a fraction of the cost. This will make them a fashionable tool designed for market research and customer studies as well as mental health research. However , despite their a large number of advantages they come with some cons which can challenge the quality of the outcomes.
One serious problem is that generally there is less control over data capture than with a paper questionnaire. With a Net experiment the participant is able to view stimuli on their own personal device and could also improve settings including screen size, internet browser, internet connection as well as the default font. Consequently that every respondent activities a subtly different customer survey and this can affect how they answer questions.
Another problem is questionnaire taking fatigue which can lead to respondents abandoning the survey. The way to steer clear of this is to make the questionnaire while short as is feasible and only inquire abuout that are relevant to your research. Also you can try to randomize the order of the questions and pretest the questionnaire ahead of performing this to ensure that the questions are very clear and understandable.
Finally, you will need to keep in mind that Web experiments depend on voluntary contribution so they can be susceptible to motivational confounding than laboratory tests. To counter this kind of, you can use a web marketplace just like SONA devices (often intended for undergraduate screening at universities), internet-based.org/questionnaires-as-a-poll-instrument MTurk or Productive to recruit participants.
