I made 20 questions here and randomized them. I only display 1 of 20 questions to the responder. Now I see the actual displayed question to my 3 responders. All of them got the same question displayed. Basically, the effect of randomization in my design failed. What is wrong with it? (Additional information you might need: I distributed my survey to these 3 responders who are in the same contact list.)
