The workshop in brief:

The main objective of this workshop was to address the assessment of item suitability, reliability, and validity during questionnaire design using appropriate statistical methods. The workshop introduced the concept of questionnaires, highlighted their importance in research, and discussed their classification based on structure, question type, measurement scale, and purpose. It also covered different types of questionnaires and the use of Likert scales. In addition, the workshop presented statistical techniques for evaluating questionnaire items, including the Shapiro–Wilk test, Cronbach’s alpha, item–total correlation, KMO test, Bartlett’s test, factor analysis, Mann–Whitney test, and Kruskal–Wallis test. Finally, methods for effectively presenting questionnaire results using graphical tools such as stacked bars, diverging Likert charts, radar charts, and word clouds were demonstrated.
