About this Gig
I Will Ensure Your Suestionnaire/Survey Shines: Validity & Reliability Analysis for Flawless Data "Quality In, Quality Out. Garbage In, Garbage Out!"
A well-designed questionnaire generates gold-standard data that drives actionable insights. A poorly constructed one? Garbage data that wastes time, money, and research potential.
With 30+ surveys designed and analyzed across psychology, management, education, and business, I'll ensure your questionnaire delivers reliable, valid, and statistically robust results.
What I Offer:
- Cross-cultural adaptation & translation: Ensure consistency across languages and demographics.
- Reliability: Cronbachs alpha, McDonalds omega, and more.
- Validity checks: Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), and more.
