Hi,

I took several days with LimeSurvey and I like the most things. Now I'm trying to do a survey for a high-school of this type:

Question 1:
The credit 01 is...

A1:Good
A2:Normal
A3:Bad

Question 2:
The credit 02 is...
A1:Good
A2:Normal
A3:Bad

Question 3:
The credit 03 is...
A1:Good
A2:Normal
A3:Bad

...

So that I want is two types of statistics.

1- statistics for each question (total of Good,Normal,Bad). This, the LimeSurvey do it perfectly.

2- statistics for all survey, in other words, the total "Good, Normal and Bad" of all the questions, adding the same answers to total survey.

Sorry for my english and sorry if the question was answered, I searched and nothing found.

Thanks,

Hello,

LimeSurvey aren't a statistics tool, but here you can use another questions, maybe 3 equation question type.
And the equatio can be :
- SUMGOOD : {sum(Q1.NAOK=="A1",Q2.NAOK=="A1",Q3.NAOK=="A1")}
- SUMNORM : {sum(Q1.NAOK=="A2",Q2.NAOK=="A2",Q3.NAOK=="A2")}
- SUMBAD : {sum(Q1.NAOK=="A3",Q2.NAOK=="A3",Q3.NAOK=="A3")}

Hi DenisChenu,

Thanks for the help! I don't know much about equations and I has studied it more. However the values "SUMGOOD, SUMNORM, SUMBAD" or any value, only it saves the value in the current survey which user is answering?

user1 answer:
Q1: Good
Q2: Good
Q3: Bad

Your equation results:
SUMGOOD: 2
SUMNOrmal:0
SUMBAD:1

user2 answer:

Q1: Bad
Q2: Good
Q3: Bad

Your equation results:
SUMGOOD: 1
SUMNOrmal:0
SUMBAD:2

So I have two questions of this... the values SUMGOOD/NORMAL/BAD are erased on start of each survey no? There is any way to save the value of last answered survey by the last user and increase it in the current survey? The value SUMGOOD/... is saved in database until the survey is expired/desactivated or only temporaly until user finish the survey?

And another question, for my survey I thought to do a vector.

Good Normal Bad
C1---[]--[]
[]--
C2---[]--[]
[]--
C3---[]--[]
[]--

So when I generate a statistics of this the results split by C1,C2 and C3. There are any way that using equations and values (SUMGOOD..) that could show me the C1,C2 and C3 like one, no split?

Thanks again and sorry if I'm annoying...

Each survey answer are separated. There are no link betwwen each answer.

To have this fuctionnality, you have to hack the code or use ajax. But it's a php/javascript dev job.
