Questionnaires can be used to collect data for a research study. Some questionnaires use both open and closed questions and others mix the two. Open questions give the respondents to respond in their own words. Closed questions offer an answer list that they can select from. Questionnaires can be administered via postal mail, phone or online.

Online questionnaire surveys are becoming more popular, but it’s crucial to make sure that the information gathered is valid and reliable. To accomplish this researchers must accurately gauge response rates and determine the number of people who complete the survey. The researcher must also be able to identify the reasons that a person might not be able to respond and take steps to address these issues (e.g. sampling bias).

Additionally that the cost of conducting online questionnaires is less than that of traditional methods which makes them an attractive alternative to traditional questionnaire-based research. This method comes with difficulties. Online questionnaires are difficult to evaluate in terms of their validity and reliability and can have social desirability impacts on the respondent samples.

There are several strategies to limit these limitations. This article provides a number of specific strategies that can help researchers improve the quality and reliability of their online questionnaires, for example: (i) paying participants when they are finished with the questionnaire has less responses than waiting for all responses or a middle procedure; (iii) asking participants to provide their names for receipt preparation does not decrease or improve the social acceptance of answers as well as (iv) framing the fixed portion of a participant’s payment as being „for filling out the questionnaire” and offering progress feedback improves the quality of answer.
