Questionnaire Design and Validation using R

This session is designed to equip researchers with comprehensive knowledge about questionnaire methodology - a critical area frequently scrutinised during thesis and research project evaluations. Participants will learn to confidently explain their instrument development process, distinguish between different questionnaire types, and demonstrate proper validation techniques using R packages (psych, lavaan, GPArotation). The webinar covers reliability testing using Cronbach's Alpha, McDonald's Omega, KR-20 test and hands-on R implementation. Perfect for researchers, postgraduate students, and academics seeking to strengthen their research methodology foundation and defend their work with confidence. Sponsored by R Consortium and organised by Unijos R Users.
