Questionnaires are a vital tool for primary research that can be quick, efficient and easy to use. A good questionnaire should not be too long, use plain English, and have questions that are simple and straightforward. Questions should focus on what is essential to know, be useful, and avoid unnecessary information. It is important to consider open and closed questions, with open questions allowing more depth but being harder to analyze, and closed questions allowing for quicker responses and easier analysis. An introduction to the questionnaire should explain its purpose, importance, how results will be used, and contact details.
