hi all, I'm starting off with LS and was hoping someone can help with the correct terminology or method so I can do more research through the docs.

I would like to present 9 questions.
Each question is a choice answer.
Each question is 2 column permutation of specific characteristics, of which one needs to be selected.

I have preset permutations to load into the tables for each questions. [What is this called?]
What's a good approach here, as the characteristics will be made up of text and a graphic.

It get's a bit more involved further re the presentation and randomization of questions.

It'll try and explain it like this:

a Set = 9Q's
question 1 has 5 permutations, BUT the permutation is linked to specific permutations of the other 8 questions.

Question 1:
| Option A | Option B |
size {varXX}: | L {varXx=l} | M {varXx=m} |
colour {varXz}: | Blue {varXz=B} | Red {varXz=C} |
neck {varXy}: | Polo {varXy=P} | Round {varXy=R} |

Which do you prefer? A or B

Question 2:
| Option A | Option B |
size {varXX}: | L {varXx=l} | X {varXx=x} |
colour {varXz}: | Red {varXz=C} | Blue {varXz=B} |
neck {varXy}: | Square {varXy=S} | Polo {varXy=P} |

Which do you prefer? A or B

....Question 9

So the 1st 'group' will have:
Q1 = A[{varXx=l},{varXz=B},{varXy=P}] + B[{varXx=m},{varXz=C},{varXy=R}]
Q2 = A[{varXx=l},{varXz=C},{varXy=S}] + B[{varXx=x},{varXz=B},{varXy=P}]...Q9

<then random function for next user> so they get a different group, say
'group 4'
Q1 = A[{varXx=l},{varXz=C},{varXy=S}] + B[{varXx=m},{varXz=C},{varXy=R}]
Q2 = A[{varXx=l},{varXz=B},{varXy=P}] + B[{varXx=x},{varXz=B},{varXy=P}]...Q9

and so on.

Ideally I would like to
1. load in the available options for each variable (Global range)
2. then program each group to display specific permutations of the variables


I need to be able to collect the data of the specific preferences between A and B per question and in relation to other questions in the same 'group'.

- There are other requirements as well (further randomization and a control question to help prevent random responding), but may confuse the issue at this stage.
I think if someone can help me with the correct names and concepts and can get it done.
Thanks!

Hi pietpomp,

I'm not really sure I can catch your concept. Do you like to show randomly one other permutation for every participant or do you like to show one participant more than one permutations (randomly of course)?

mmm not quite orvil,

each question is a choice question between option A or B ("Please select your prefference").

each question has 5 permutations/versions
Q1a, Q1b, Q1c, Q1d, Q1e

each permutation is a different combination of size,colour&neck for option A and B

each participant gets a set of 9 questions.

each set has a specific variation of the question permutations,
set1: Q1a, Q2d, Q3b...Q9c
set2: Q1d, Q2c, Q3d...Q9e
set3:
set4:
....set(n)

that's the basics.

So whether participant gets set1 or set2 is the next level/layer of the challenge ~ not dealing with that now.

Hope it's a bit more clear now?

ah, now I think I've got it!

Have to do some mental processing.... (brain server load 99%
