The following represents questions one should ask when creating a questionnaire.
What does the question contribute?
Each question included in the questionnaire, should contribute significantly to acquiring relevant information for the researcher. The questionnaire should be assessed prior, so as to ensure that all the questions present are relevant and if not, irrelevant questions removed.
Over the years doing data entry, data analysis and interpretation of results for students, lecturers and companies; We have come to concluded that questionnaire design is one of the most critical element of any survey type study (studies where questionnaires are used to collect data). The questionnaire can make or break your data analysis, so pay attention!
We have seen the good, the bad and the indifferent, as it relates to questionnaires. The good ones always include: Obvious headings, clear instructions as to what should be done to complete the questionnaire, concise questions, and most importantly, the questions asked, should adequately address the hypotheses being tested – the main issues or problems being examined.
