Questionnaire survey is the most common choice of research methods for students who write not only bakalark, a diploma, a dissertation, but also a rigorosum or a paper.

The questionnaire represents a written form of structured interview. It consists of a header where the author introduces himself, addresses the respondents and informs them of the purposes for which the information from the questionnaire will be used. Then there is the main part where the respondents will find questions and answers. And at the end of each questionnaire, the author should thank the respondents for the time and willingness of the respondents.

Where to start?

Before you start compiling the questionnaire, you should think about what you want to investigate through a questionnaire survey. Determine hypotheses that will be closely related to the goal and the entire theoretical part of your final thesis (bakalarka, diploma, dissertation, etc.). These hypotheses will be crucial for you and will be based on a questionnaire survey.

Consequently, you will definitely find the target group of respondents, the form of the questionnaire and the type of questions. Consider that your respondents will certainly not want to deal with a questionnaire that is enormously large. Therefore, there should not be too many questions, otherwise the respondents are at risk of passing your questionnaire superficially and ticking off the first answer they see.

When composing questions, consider not only the hypotheses set, but also the specific qualities of your respondents (age, gender, social background, education, etc.). Questions should be compiled according to the so-called funnel, ie – the questionnaire begins with a general question, the following questions gradually narrow down, concretize and point to one subject.

Remember that the way you ask questions is the answer

Questions in the questionnaire may take various forms. The most common questionnaires are a combination of open, closed and semi-closed questions.

Open query type

The respondent decides what to write in his answer. Open questions allow deeper insight into the observed phenomena and better reflect the respondents’ true views and attitudes. The processing of such kind of questions is more laborious, but the information obtained is more valuable.

Closed type queries

They offer the respondent a choice between two or more alternatives. The respondent is presented with ready answers without the possibility of expressing subjective opinions.

Semi-closed query type

This type of question allows the respondent to complete or clarify the chosen answer.

Reliability and relevance of the questionnaire

The reliability of the questionnaire depends on the intrinsic consistency of the questionnaire. The reliability of the questionnaire survey is higher when the questionnaire contains a number of questions that ask for the same. The greater the range of respondents and more aptly the questions, the higher the relevance of questionnaire research. The minimum questionnaire return required is at least 75%.
