Hi, I have two questions about design with picture and randomization. Hope you guys can help me out. Thank you.
1. My questionnaire has a picture in the beginning and followed with 30 questions, which have to be answered based on the picture. Since the questions are a lot, participants have to scroll back to see the picture when they answer some questions near the end. I wonder if there is any method that I can make the picture on one side and question on another side and let the picture go with the questions? For example, when participants scroll down the questions, the picture will go with the scroll down and still shows on another side of the questions.
2. There are couple of groups (a pictures followed with 30 questions) in a questionnaire. I wonder how to randomize the groups, as well as how to randomize the 30 questions in every group?
Thank you very much. I have stuck with them for a while.
