QS : ordre aléatoire
From LimeSurvey Manual
Random answer order (random_order)
Attention : The order of randomization is currently not stored. So if the user is given the option to save/resume later the order will randomly change on resume.
Description
This attribute causes LimeSurvey to ignore the existing order of answer options/subquestions, and instead it orders them randomly. It is important to note that this random order will be reordered each time the question is displayed. So, if someone returns to a question, the order will probably be different from the first time she saw it. This option permits the survey creator to diminish the survey bias. Please note that if a question has subquestions, the order of subquestions will be randomized, not the order of the answer options.
Available options
- Yes - Randomize on each page load
- No (default)
