If you decide in your bachelor’s or master’s thesis to write a practical, application, or empirical part, you will inevitably have a decision on how to accommodate that part. One of the options is a questionnaire survey, which can be part of both qualitative and quantitative research.
The questionnaire survey is a method that is not suitable for all types of research. If you are still considering whether to use a questionnaire or an interview, some things need to be clarified. The first is the purpose of the research. Do you need only a few respondents to confirm your research assumption, or do you need a large number? Do you just have answers from respondents in your area or do you need to cover a larger area? Will respondents be able to respond in writing (eg seniors)?
Are they mature enough to understand the questions (little children)? Your choice of questionnaire also plays a role in your time options etc. So the questionnaire is useful wherever it is necessary to have more respondents, it is assumed that respondents will be interested in responding sincerely and truthfully, trying to save time or money. However, the overall research concept should always be considered.
However, the creation of the final questionnaire is not easy and one cannot ask one question after another. Before starting to create a questionnaire, it is necessary to set hypotheses or research assumptions on which the questionnaire will try to find answers leading to their verification. When compiling a questionnaire, it is also necessary to take into account what you write in the theoretical part of the thesis, because it is not possible to ask a question in a questionnaire about any matter that you have not mentioned in the theoretical part of the thesis. Here too, be careful about linking content. If you do not succeed, or do not dare to do so, have a look on our website.
At the beginning of each questionnaire, respondents should be informed about the purpose of the interview, the interview process (whether they should always only have one answer, or more, etc.) and assure them of anonymity. The questionnaire usually includes identification questions (gender, age, education, etc.). Sometimes it is recommended to leave them to the end so that they do not poison the respondent and do not discourage the filling. At the end of the questionnaire, the respondent should be thanked for his time and willingness.
The optimum number of questions in the questionnaire differs according to the purpose of the research, the number of hypotheses set, but in general no more than 20 to 25 questions are recommended, so that the respondent does not lose interest again and the questionnaire does not fit into the basket in the middle of the questioning. Also important is the graphic layout of the questionnaire and its clarity! Even with this we are able to help you.
The questionnaire has a high risk of return, which can be quite low, especially in the case of non-personal interviewing. It is necessary to reckon with it and it is suitable to even double the number of respondents than you want to get filled in questionnaires, or to respond to emails several times, etc. 100 respondents are considered optimum, but there are 30 respondents or others where need to reach 1 000 respondents.
