Questionnaires and web trials allow researchers to reach a far wider target audience than classic paper questionnaires, smartphone or face-to-face interviews and is conducted for a cheaper cost. This makes them a common tool designed for market research and customer online surveys as well as internal studies. However , irrespective of their many advantages they come with some cons which can challenge the quality of the results.

One serious problem is that at this time there is much less control over capture data than with a paper set of questions. With a Web experiment the participant can view stimuli on their own personal device and may also also modification settings including screen size, browser, internet connection and perhaps the default font. It indicates internet-based.org/advantages-and-disadvantages-of-questionnaires/ that each respondent encounters a discreetly different set of questions and this may affect how they answer questions.

Another problem is questionnaire taking fatigue which can lead to respondents leaving the study. The way to avoid this is to make the questionnaire mainly because short as is possible and only find out that are relevant to your research. You can also try to randomize the buy of the questions and pretest the questionnaire just before performing that to ensure that the questions are apparent and understandable.

Finally, you will need to keep in mind that Net experiments derive from voluntary engagement so they can are more susceptible to motivational confounding than laboratory experiments. To counter this, you can use a web based marketplace such as SONA devices (often employed for undergraduate tests at universities), MTurk or Prolific to sponsor participants.
