How to randomize answer options but keep the order afterwards?

Question

Hi there,

I have a 2 questions, each with the same set of possible answers, which should be displayed randomized in the first question but the same order should be displayed in the second questions.

For example:
1. X
2. Y
3. Z

Randomized in Q1:
1. Z
2. X
3. Y

Continued in Q2:
1. Z
2. X
3. Y

So in the end, the answer list of Q2 should be a hard copy of the randomized order in Q1.

How do I do that? Any suggestions?

Thanks in Advance

Answer 1

Create a constructed list that uses your X-Y-Z list as its parent.  Give the constructed list this code:

Add(list1)
Randomize()

"list1" should be replaced with the name of the parent list.

Finally, set Q1 and Q2 to use your constructed list.

Spot on as always Zachary.

Note the following ...

1/ If you use AIC, that will keep the randomisation order the same too.

2/ And if you use different constructed lists but need to keep the randomisation the same, use seeds within the randomize() function.

Seeding is a great way to produce consistent randomization.  Using something like the respondent number as a seed will result in a single respondent always getting the same result, but other respondents getting an entirely different result.

Really, you can stick together any 2+ parameters to get consistent randomization that is unique to those parameters.  For example, if I want consistent randomization per respondent per page, this is the seed I'd use:

RespNum() * 1000 + PageNumber()

Makes sense. Appreciate your comments Zachary.
