Create Array 5 Point Choice with Random number, category and maximum score was created by Maverick87Shaka
Hi,
I'm lost in front a this particular request. I'm pretty sure we can do it inside limesurvey since you can do pretty everything mixing javascript and native function, but I'm little bit lost in front of this needing.
What I have to do is create an unique array style question, for rating from 1 to 5 some statement. The whole "database" is build up from 15 statement for each categories, the total categories are 4. For now it's pretty linear Array 5 point choice question type.
The two main problem are:
1) they don't want to show all the 15 statement, but only 5 for each category, randomly picked from the whole database and also have a randomized order of them.
So it will be a 20 subquestion statment to rate.
2) they want to create a maximum score basket, for example 60 points, so you basically can't answer 5 to all 20 statement. The current total sums of points should be always visible from user while it's filling up ( top of the page or whatever )

Someone have some idea? I'm little bit lost in front of this reqeust hahahah.

p.s. the result expected is to have the value of points for each category, and category should not be "visible" to user while is filling up the questionnaire.

Thanks!

Hi,
create a question of type "short text" and insert the following script
Code:
<script type="text/javascript" charset="utf-8">
 
function shuffle(array) {
  var currentIndex = array.length, temporaryValue, randomIndex;
 
  // While there remain elements to shuffle...
  while (0 !== currentIndex) {
 
    // Pick a remaining element...
    randomIndex = Math.floor(Math.random() * currentIndex);
    currentIndex -= 1;
 
    // And swap it with the current element.
    temporaryValue = array[currentIndex];
    array[currentIndex] = array[randomIndex];
    array[randomIndex] = temporaryValue;
  }
 
  return array;
}
 
 
$(document).on('ready pjax:scriptcomplete',function(){
// Fill the array
      var arr1 =["01","02","03","04","05","06","07","08","09",10,11,12,13,14,15];
      var arr2 =[16,17,18,19,20,21,22,23,24,25,26,27,28,29,30];
      var arr3 =[31,32,33,34,35,36,37,38,39,40,41,42,43,44,45];
      var arr4 =[46,47,48,49,50,51,52,53,54,55,56,57,58,59,60];
      arr1 = shuffle(arr1);
      arr2 = shuffle(arr2);
      arr3 = shuffle(arr3);
      arr4 = shuffle(arr4);
      anumbers = '#,' + arr1.slice(0,5).join(',')+ ',';
      anumbers = anumbers + arr2.slice(0,5).join(',')+ ',';
      anumbers = anumbers + arr3.slice(0,5).join(',')+ ',';
      anumbers = anumbers + arr4.slice(0,5).join(',')+ ',';
      $('#question{QID} input[type="text"]').val(anumbers);
  //    $('#question{QID}').hide();
   });
</script>

As you see we create 4 arrays, shuffle them and take the first 5 elements.
You will get a string like this
,13,01,04,09,03,30,25,29,16,22,33,41,43,31,37,60,54,48,53,51,
The leading and trailing comma are important.

Now you may set the subquestion relevance of each item
strpos(Q1,',01,')>0
strpos(Q1,',02,')>0
strpos(Q1,',03,')>0
...

and randomize the dispolay of the subquestions.

Nice!

One suggestion that would allow you to place the hidden control question in the same group as the array...

Change this line:
Code:
$('#question{QID} input[type="text"]').val(anumbers);

To this:
Code:
$('#question{QID} input[type="text"]').val(anumbers).trigger('keyup');

This will fire Expression Manager after loading the hidden input, triggering relevance.
Cheers,

This is absolute an amazing starting point, and works well.
I've just a "problem" using standard array instead 5 point choice with random display option on, all the rating answer option are mixed up, not only the subquestions order. Since it's a really "scale" vote that you have to provide, it's not comfortable for the user.
But your idea works really well also with question type "Array (5 Point choice)", but I've a problem with this question type and my hosted limesurvey, the random and mandatory option are not saved. When I hit save button, the page reload and I found again my question not randomized and not mandatory.

On top of that, I still need to manage the "total score", so I have to sum all the value given in the array somewhere, and warning ( with no option to submit ) if you exceed 60 total point assigned to subquestions.

all the rating otopn are mixed up

What do you talk about?
The subquestions? Of course it is.
You said

and also have a randomized order of them.

Or do you want to have the randomization within the categories.
Then you should consider a different design.

the "total score", so I have to sum all the value given in the array somewhere, and warning ( with no option to submit

Calculate the sum and validate. But in this case you really should use a "normal" array with numeric answer codes.
Then {sum(self.NAOK)<61} is sufficient

I mean that using normal array with randomize option, make also the answer option scale 1,2,3,4,5 mixed up and not only the subquestions.

Any tip to do it? And also make it visible all the time for the user, like in the help section something like "34 of 60 points assigned"

Hi,
1. the randomization of answer options is reproducable (at least in 4.1.4.)
Seems to be a bug.

2. Something like that?
Here the requirement was: max. 100% - show the remaining %




Open a new topic about that in the German part to avoid the language gap.

Definitely something like this, but even "simpler" with just numeric sum without have it expressed in %.

btw I don't speak German :whistle:

Hi,

btw I don't speak German

Yes, I was a bit confused as I saw the German message in your screenshot.
Now I realized that this message depends on the language of the survey, not the language of the GUI.

Okay, it's quite easy.
1. You have numeric codes of your answer options, like "1","2","3",... that represent the points
Then insert into the queston text just
{sum(self.NAOK)}
You will see that this is expanded to {sum(Q2_SQ001.NAOK, Q2_SQ002.NAOK, Q2_SQ003.NAOK, Q2_SQ004.NAOK, Q2_SQ005.NAOK)}
www.limesurvey.org/manual/Expression_Man....27that.27_variables

And in your question validation equation accordingly sum(self.NAOK)<61
You may insert a question tip of your choice like "Don't distribute more than 60 points"






2. You may use the assessment values, though I do not see an advantage, except:
You want to keep the answer codes in your database but calculate the points differently.
Then you have to use
{sum(self.valueNAOK)}

In this example I set the assessment values "-5", "-2", "0", "2","5".


3. If the points are calculated differently in each subquestion, you can't use the "self" operator, but have to calculate "one by one", like
{sum(if(Q1_SQ001.NAOK==1,-5, if(Q1_SQ001.NAOK==2,-2, if(Q1_SQ001.NAOK==3,0, if(Q1_SQ001.NAOK==4,2,5)))), if(Q1_SQ002.NAOK==1,20, if(Q1_SQ002.NAOK==2,15, if(Q1_SQ002.NAOK==3,10, if(Q1_SQ002.NAOK==4,5,0)))),...
This will be really long.

Amazing Joffm, All the logics are there, now I'm playing it expanding and putting together but definitely something that I can do with Limesurvey! Thanks so much!
EDIT 2: Ok no lucky with this concept.
Adding around 300 subquestions ( that is the total database for my assesment ) I've horrible performance when reaching array question.
It's don't take so much time to load up all of them, and then clear the one based on the first question string, but it's become terrible trying to assign a value to each subquestion, it's stay really long on each click. Almost unusable experience.
EDIT3: even if it's the solution of the scoring system, adding the {sum(self.NAOK)} in the question text or the sum(self.NAOK)<61 in the validation equation is causing a tremendous lags of the system, making it impossibile to se and fill up from a user.

There could be something different that I can try?

Using the whole database of 300 subquestions in the Array 5 point, and selecting 60 of them with the javascript to build a "random "string in the short text question works fine, it's not causing trouble.

The performance impact comes when I try to use {sum(self.NAOK)} in the question text or sum(self.NAOK)<150 in the validation equation.

Any tip or idea on how to avoid this performance problem?

Here you have only this question with 263 subquestions and relevant equation setup for this javascript:
Code:
<script type="text/javascript" charset="utf-8">
 
function shuffle(array) {
  var currentIndex = array.length, temporaryValue, randomIndex;
 
  // While there remain elements to shuffle...
  while (0 !== currentIndex) {

    randomIndex = Math.floor(Math.random() * currentIndex);
    currentIndex -= 1;
 
    // And swap it with the current element.
    temporaryValue = array[currentIndex];
    array[currentIndex] = array[randomIndex];
    array[randomIndex] = temporaryValue;
  }
 
  return array;

      arr1 = shuffle(arr1);
      arr2 = shuffle(arr2);

      arr4 = shuffle(arr4);

      $('#question{QID} input[type="text"]').val(anumbers);

It works well until I put the code to make the score point {sum(self.NAOK)}

I made more tests to understand which is the real limit in terms of performance that can i try to push for this assesment with Limesurvey.
The "Limesurvey" way doesn't work in terms of performance, even if I try to pick up "only" first 60 subquestions in a static way to make the test,using:
Code:
{sum(G01Q06_SQ001.NAOK, G01Q06_SQ002.NAOK, ...}
Instead picking all the 273 subquestions database with with
Code:
{sum(self.NAOK)}
the performance remains really low, client browser freeze after making a selection. The performance are "better" then all complete sums, but it's not usable anyway.

I really don't know hot to approach this problem, i was hoping that avoid the whole sums can solve the problem, but it's seams is not like this.

Hi,
You seem to use version 4.x., don't you.

I can reproduce your issue in 4.x.. But no idea about it. I use 4.x. only to test. But it is considered here several times as "slow", "very slow", ...

I do not see any issue in 3.x LTS. No performance issue with 270 items.

Sorry, I am not able to help.
