hello from Brasil!
I am planning to make a survey where I will show on each question a different text randomly chosen from a saved sample of “n” texts. I will ask respondents about their perceptions about the text.

is this possible with Limesurvey? How?

thanks a lot

If you have a small number of text strings, you can use ExpressionScript to generate a random number and display the corresponding text string.

Otherwise, you may need to use JavaScript to import a CSV file.

Searching the forum (or Google) should yield many examples.

How much is "n"?
And how many questions do you want to ask?
 

Good question!

I am working with "access of information" requests, so, N will me around 100, and each request (single text) can vary from 10 to 1000 words. So, texts are more likely to be long than short texts.

Thanks a lot

Hi, an easy way without javascript would be to store the texts as default answer into a question of type "huge text" (QText)
Maybe with this beginning
#00100021This is my first text#00200040And this is my second text, a bit longer#003....
Meaning: three characters to define the text number and five characters to define the length of this text.

Now you create your random numbers (rn) and find your text with these three equations
eqStart:  {strpos(QText,'#'+rn)}
eqLength: {substr(QText,eqStart+4,5)}
eqText: {substr(QText,eqStart+9,eqLength)}

One obstacle:
The "text" type only allows up to 65000 characters.
So if your texts are longer in total you have to use two or even more of them.

Best you provide a lss export that shows your scenario.
