Block randomization | XM Community
Skip to main content
I have 22 blocks, I would like to randomly select 11 of the 22 blocks for respondents to answer, subsequently I would like ask a few questions then randomize the remaining 11 blocks. for respondents to answer. So the sequence is:



1. 11 randomly selected blocks

2. Matrix question

3. Remaining 11 blocks randomized
The process for this in the survey flow would look like this is...



1. Randomizer with all 22 blocks nested below with (11) as the number of blocks to display.

2. Block with your matrix question(s)

3. Branching logic for all 22 blocks that says "Display if (question in given block) has not been displayed". This will make it so none of the previous 11 blocks are shown. This sounds like a lot but it is not a hard setup. Best practice alert I would group all these branches in a Group block so that you can collapse them all when looking at your Survey Flow.
