Hello,

I have two short questions regarding randomizing questions:

1) I will have 5 questions I want to randomize but when analyzing the results I want to be able to know in which order the randomized questions were asked. Is this information saved in the database for evaluation?

2) My 5 conditions always come with a secondary question that has to follow the main randomized question. So the format is R1-S1 R2-S2 R3-S3 R4-S4 R5-S5 and I want them randomized e.g. to R2-S2 R4-S4 R1-S1 R5-S5 R3-S3 (so the second question always has to follow the randomized one but has to match it. Can this be done and if yes how because the randomizing function seems to focus on having just the R1 R2 R3 R4 R5 randomized in order but I need the following S1-S5 question before the next randomized question is asked.

Thanks for any help

Assuming all questions are in the same group and you are using group-by-group mode...

1) No, this is not recorded. You could add a short-text question to the group and use JavaScript to hide it and load it with the question IDs in order of display. Add a script like this in the source of the short-text:
2) You can use a script in the source of each randomized question to dynamically move the paired question to follow it. Something like this to move a question with ID 123:

Thanks for the elaborate answer to my 2 questions. During this day I actually realized that it would probably be easier if I simply shift my 5 twin-questions one level up and turn them into 5 new question categories and just use the category randomization on these 5 twin-questions.

But I guess I will still need an easy fix for recording the order of these 5 randomized questions. Probably the easiest would be to add a hidden question to each of the 5 new categories and have a time stamp automatically added as an answer to each of these 5 hidden questions. Then I can just look at these time stamps to figure out, which questions was asked when.

Is there an easy way to copy the date/time stamp into the answer of a hidden question?

Good idea!

Is there an easy way to copy the date/time stamp into the answer of a hidden question?

You can use an expression type question:

date + time => {date("d/m/y H.i.s")}
only time => {date("H.i.s")}

Use php date format to match your needs

Ok thanks to both of you. The reconstruction of the randomized order from the time stamps is working just fine.

I had one interesting effect which I've not quite understood: I had to copy the survey so I could publish it and thus check if the time stamp recording is working and it worked just fine but I realized that the randomization which worked before copying the project suddenly did not work anymore on the published version. I tried twice and always got all questions without randomization. Since the randomize group name was still entered in all 5 question groups I could not see why that should happen, so I simply deleted the copy and did exactly the same thing again, copy the project, publish it and then randomization was working as expected. I've not changed any options when copying the project in both cases so I'm not sure why it didnt work in the first case. I'll try again a few times over the next days and see if it happens again...
