Hello,
please, I need some help in randomizing.
I have 50 different pictures as stimuli. And 12 different questions on a rating scale for each of the 50 pictures. In total 600 questions. Right now, my script shows picture 1 for 12 times, then picture 2 for 12 times and so on. But what I want is that each participant gets a different order of the 50 pictures. For example: participant A starts with the 12 questions to picture 1, then 12 questions to picture 10, then 12 questions to picture 8 …. ; participant B starts with 12 questions to picture 32, then 21, then 18 ….
I hope I made myself clear. I appreciate your help! Thank you so mch fpr your help!
This is my script:
<item houses_2>
/1= "Slide01.jpg"
/2= "Slide01.jpg"
