A good questionnaire is friendly, easily readable and able to be easily understood by the respondent. It should also have open-ended questions that do not restrict respondents to limited answers. According to PreserveArticles.com, respondents can express themselves fully to relay the intended message. A good questionnaire should also be attractive because respondents may lack interest if less attractive designs are used. The items should be logically sequenced with simple questions.
A good questionnaire is based on the specified objectives a researcher intends to achieve. It also has directions for respondents as they answer questions. Directions in this sense imply the manner in which questions are to be answered and how the responses score. Direction should also be given regarding where the filled questionnaires are to be returned and by what methods. A good questionnaire also has a statement on confidentiality. This assures respondents their answers and identity will not be shared. Measurability is the other quality of a good questionnaire. The responses received from participants must be measurable. This measurability is important, as it enables researchers to extract specific information, data or statistics from the questionnaires. Hence, quantitative results and analysis can be done. The sequence of the items in a questionnaire should also flow logically to avoid confusion.
