Dear community,

I have a question regarding a survey I want to run in LimeSurvey.
First, I have three different comparisons that I would like to run:

•     method_1 vs. method_2 (M1VSM2).
•     method_2 vs. method_3 (M2VSM3)
•     method_1 vs. method_3 (M1VSM3)

For this I have created three different questions (I don't know if that is sufficient). However, I want to make these comparisons, say, 10 times with randomized content. So the first question (M1VSM2) should be visualized 10 times with different content, then the second question (M1VSM2) 10 times with different content and the same for the third question. The different content means that I have 50 trios of images (img_orig_1, image_m1_1, and image_m2_1; img_orig_2, image_m1_2, and image_m2_2, ...), of which only 10 trios should be (randomly) displayed to users. For each trio I want to visualize all three images side by side and the order should be random again, except for the image img_orig_X (must always be the first image). So the following options should be possible [img_orig_X, image_m1_X, image_m2_X] and [img_orig_X, image_m2_X, image_m1_X]. The user should be able to select either the image in the middle or the image on the right (either image_m1_X or image_m2_X).

Should I define three question groups for each comparison and than 10 questions with the same textual content?

Is this something that could be done in LimeSurvey?
How should the image trios be orginized in the cloud to make it easier to program the survey?

Thank you very much in advance!

Kind regards,
dj

Actually it would be better to have three radio buttons, for the following options: "Img1" (e.g. image_m1_X), "Img2" (e.g. image_m2_X) and "Both". However, the logic of the question should keep the relationship between the anonymous label "Img1"/"Img2" and the actual image of the two different methods image_m1_X/image_m2_X. Thus, we can evaluate this statistically later.

Hi,
1. 10 out of 50
Create two groups
Hide the second group
Put the first ten questions into group1, the rest into group 2
Give the same randomization group name to ALL 50 questions.

2. Display of question
 
There are two javascript snippets in the sample file.
The first shuffles the second and third image randomly.
The second places the orig image into the upper left corber of the array.

Dear Joffm,

thanks for your quick reply!

ad1) do I have to specify all 50 questions by hand? Actually, the question is same in all 50 cases, except that the images are different...

ad2) is it possible to have radio buttons in a vertical way:
+ method 1
+ method 2
+ both

Thank you very much in advance!

Kind regards,
dj

Hi,
1. LimeSurvey does not support loops. So: yes
2. Less appealing - in my opinion, but

Thank you very much!

Is it possible to load a question from e.g. a txt file containing the whole source code for a specific question?

Kind regards,
dj
