Hello, 

I am planning to do an online Delphi survey. In the first round, respondents will be asked to evaluate situations with rating scales.
In the second round, respondents will need their responses from round 1 and the median value of all raters for each scale. 

How do I display their Round 2 responses with the median of all raters?

The question has already been asked on the forum but I don't understand the answers (not detailed) and I am new to limesurvey.

Thank you. 

Juline. 

Hi, Juline,
so you have two surveys. (1st round & 2nd round)
What type of survey are you planning? An open survey or a closed survey?

I should say it is a closed survey,
So you may calculate these values after the first round and add them as additional attributes to each participant of the second round.

Anyway, you should describe your survey design a bit more detailled,

The question has already been asked on the forum but I don't understand the answers (not detailed) 

Here it would have been better to include the link to this thread.


Best regards

As Joffm says. But, as the median is the same for all respondents, you could also include it already in the survey, which could be easier or more complicated, depending on your survey structure and how you want to display it.

Thank you for your answers.

To detail my study: 
1) we give several situations to the participants who will have to evaluate with a rating scale (1st round)
2) We collect the results of all participants to have the median.
3) We communicate with the participants the median and their results (2nd round)

In the second round, we repeat the questionnaire to the participants, displaying their answer (from the first round) and the median of all participants. 

My real question is in the 2nd round, how do I get each participant to display their answer from the 1st round?

Here is the link to the forum where I don't understand the detailed answers:

Hi, Juline,
You did not mention which version of LimeSurvey you are using.
This hier refers to 3.x.

1. If you are not allowed to use plugins, it's not necessary to read this first solution.
Well, you may use the plugin "updateTokenByResponse"
[url] gitlab.com/SondagesPro/TokenManagement/updateTokenByResponse [/url]

Now I use only one survey.
In the participant table I create 8 additional attributes (my example has only 4 questions)
 

In the plugin settings "Simple Plugins"
I set which question are to save into these attributes.
 

Now I prepare the text of my questions (subquestions)
Like:
Subquestion 1 <span style="color:maroon;font-size:8pt">{if(!is_empty(TOKEN:ATTRIBUTE_1),"<br>You rated "+TOKEN:ATTRIBUTE_1+ " in the 1st survey<br>The median of this subquestion was "+TOKEN:ATTRIBUTE_5,"")}</span>

As the "TOKEN:ATTRIBUTE" is empty in the first round, this second part ("You rated ...") is not displayed in the first round
 
but the values are stored into these additional attributes.

Aftter the first round export the data and delete all responses in the answer table
 

In the participants table update the participants
 
In the general tab update these two values
 
In the additionl attributes tab add your calculated medians
 

Now the survey is ready for the second round.
The "old" entries and the median are displayed.
 


As @holch already said, it is not necessary to use an additional attribute for the median.
You could use a hidden question of type "multiple short text" and enter the medians as default value.

2. Without the plugin you could download the participants table, add the values into the additional attribute columns, delete the old participants table and upload this new one,
with only the needed columns.
