Questionnaires and web tests allow researchers to reach a far wider audience than classic paper questionnaires, cellular phone or face-to-face interviews and can be conducted at a fraction of the cost. This makes them a well known tool pertaining to market research and customer surveys online as well as subconscious studies. However , inspite of their various advantages offered with some negatives which can undermine the quality of the benefits.

One serious problem is that at this time there is much less control over capture data than with a paper customer survey. With a Web experiment the participant is capable of view stimuli on their own personal device and can also modification settings including screen size, internet browser, internet connection and in many cases the default font. As a consequence that every respondent encounters a discreetly different set of questions and this may affect how they get suggestions.

Another problem is customer survey taking fatigue which can lead to respondents abandoning the study. The way to steer clear of this is to make the questionnaire since short as is feasible and only ask questions that are highly relevant to your research. You may also try to randomize the order of the questions and pretest the questionnaire ahead of performing it to ensure that the questions are distinct and understandable.

Finally, you have to keep in mind that World wide web experiments depend on voluntary participation so they can be a little more susceptible to motivational confounding than laboratory trials. To counter this, you can use an online marketplace just like SONA devices (often employed for undergraduate screening at universities), MTurk or Productive to sponsor participants.
