Randomize questions, question & answer groups

@JoyLaneResearch: I didn't really get situation 1. Do they want you to randomize the groups of questions (but order of questions within the groups is the same) or do they want to present several groups that contain the same questions in a specific order but randomize the questions within the group? I assume the first one, right?

Because the second one would be possible with this approach from the svn. It isn't stable though.

@holch: Situation 1 is randomize groups (pages) only.

None of my clients have requested randomizing question order within question groups (so far).

My opinion:

Randomizing the order of question groups (pages) is more urgently needed.

If we can randomize pages but not questions, I can, if necessary place one question on each page to force random question order.

However, if we can randomize questions but not pages, I don't see how I can fake a random page order.

Not sure I said that very clearly. Did it make sense?

How is it strange? It is most flexible and very easy to configure. Just edit the questions you want to be in the same rand group and enter the same freely choosable name in each question for the new randomization attribute.

The advantage is that the so randomized questions can span across different question groups (in fact the implementation is not related to question groups at all).

So for example you can pick question 1a from question group a, question 5b from question group B and question 3c from question group c, just put them into your randgroup1 and these three question will be shown in randomized oredr, but at their destined places in the survey.

@JoyLaneResearch: That is what I thought and this seems not to exist yet. The function that Mazi was referring to is basically the possibility to define a certain "group" of questions (not to be mistaken by the already available question groups). The questions in the defined group of questions can be randomized. This is already a nice thing to have, but then, as you said, randomizing question groups is a more common scenario in market research. Let's hope this will come for one of the next releases.

I agree with Carsten. This question randomization is quite simple, but flexible. First I thought it was strange too, because the example questionnaire was a little confusing. I didn't really get what it did. Honestly, at the moment I don't see many situations or research designs, would require this level of flexibility in randomizing questions the way it is shown in the sample questionnaire. But as long as you can define some questions that can be randomized, I am already happy.

I also agree that the randomization of question groups would be the more important one, as there are several survey designs that might require this. But I assume that it is more complicated to randomize question groups, than to randomize questions, otherwise they would probably have implemented it first.

And: while I currently can't really think of survey designs that would require the scenario that Carsten was describing, I can imagine that there are survey designs out there, that need this kind of randomization, I just didn't come across them, but others might need this quite a lot.

Well, this is more of a even distribution of bad results, isn't it. While it is something you might want to do if there is no other way, I highly recommend all researchers to generally improve the way they ask people, because what is the point of asking questions, where you already know that the results will be bad anyway? I know, some clients really insist, but...

It should be possible to define a group of questions, and those question should be possible to randomize.

Example:

Q1
Q2
Q3a
Q3b
Q3c
Q4
Q5

So the different Q3 questions should be randomized, while the order of the rest stays the same:

Q1, Q2 -start randomize- Q3b/Q3a/Q3c -stop randomize- Q4

The same thing should be possible with groups of questions, example:

Q1
Q2a,b,c
Q3a,b,c
Q4a,b,c
Q5

So this could look like this:
Q1 -start randomize- Q4a,b,c - Q3a,b,c - Q2a,b,c -stop randomize- Q5.

Ideally the questions within the group should be possible to randomize as well (see above).


Just wondering - how much of this has now been implemented in LimeSurvey 2.00+?

  1. I see on the "Edit Group" page there is now an option, "Randomization group". Does this mean that groups can now be shuffled?
  2. I see on the "Edit Question" page there is now an option: 'Get order from previous question.' This is a great feature. Is there any way to implement that at the GROUP level? So that if Group 1 was randomized in X order, Group 2 can also inherit this order?

We have outlined all Limesurvey randomization options at How to randomize items at Limesurvey .

There are also some sample survey we created for demonstrating the various randomization options. Here are some links:

Please note that Mazi's links are referring to LS 3.x, not LS 2.0. You should not be using LS 2.0 at this point of time. It is not supported anymore and there have been a couple of versions in between already. You should really update to a recent version of Limesurvey.

Oh man, I actually thought it was something like that and looked when this was posted, but I must have looked at the time mazi had posted his post here. To a 1000 year old post (internet years).

Anyway, if someone reads this: don't use limesurvey 2.00+ in 2019. ;-)
