Hej guys,

I'm doing a little survey (actually pretest) in the context of my master-thesis.

I have 2 different brands which can have 3 different traits. So its basically 6 different scenarios (2 brands, each 3 traits).
After a couple questions the subjects are asked to evaluate 1 out of these 6 scenarios. So what I could do is probably make 6 different question types and assign them to the subjects by random. But I don't how this will work while using SPSS later.

The thing is actually that in the question or group description I will have an image. Every scenario has its own image. So in one scenario is the brand ad is exciting, one ad is boring etc...

So like I said I would probably do it by creating 6 different questions. Each with another image and then assign them by random. Could be an advantage because then I could specify the questions with names of the brands instead of writing "the brand I showed you" or something like that.. But I was wondering if there might be another possibility and hopefully you could give me a hint. Maybe I don't need to create 6 questions and maybe I could do something where the image is combined with the brand name which then can be used in the question...Just guessing...

Thanks guys. I really appreciate this...

You should be able to use expression manager to dynamically set the source of the image.

Assuming you have an equation question containing a random number between 1 and 6, something like this:

.

Do I have to use the code in a question or is it also possible in the question description?

Let's say I have two brands (B1 and B2). I will use the code you wrote. When I export the data, will I be able to see which brand-image the subject evaluated. Because - don't know if you are familiar with it - I would like to show just one brand and then asked the subjects to evaluate their brand personality which contains approx. 20 different Items on 1-5Likert Scale. So I think I will need something (maybe a column in SPSS) that says those scores of the items are related to B1 etc...

Thanks, mate.

I don't understand the question.

Yes, you will have the random number stored in the equation question data column.

Thanks.

What should I do, if I need the random brand-logo in the group description because there 6 different questions like brand attachment, purchase intention etc. And every question should be based on the random image...? I think this is my main problem.

I would like to show the brand-image in the group description and then asked the questions...But posting it in the group description won't give the opportunity to see which picture it was, right? So I definitely need a question type to have a question later on which shows me the image number?

As I said, load the random number into a previous equation type question . This value can then be used anywhere in the survey.

I can't get it working...

I created an equation question (code= brand) with the code (with my path).

<img src="path/to/images/image-{randomNumber}.jpg">

My images are named "image-1.jpg" "image-2.jpg" etc. Is "randomNumber" something that needs to be defined before this question?

Sorry...I'm a little confused right now..

Because the subjects are not allowed to pick 1 out of 6 by themselves. It must be by random.

Well, I think I found something that's very similar to what you explained and I found also some other threads like limesurvey.com/de/forum/can-i-do-this-wi...gnment-to-conditions .

I think the easiest way would be to just use "{rand(1,6)}". Like the other members I would prefer it to have equal subject numbers per scenario? Does that mean I have to use the code in the linked thread?

Thanks tpartner!
