This is a step-by-step manual to configure a Limesurvey poll to show X questions from a (random) selection of Y question groups.

The proof of concept can be accessed here: https://survey.toolsforresearch.com/index.php/345678. The compliation was borrowed from Tony Partner:

The full manual can be found here: https://toolsforresearch.com/limesurvey-randomly-show-x-out-of-y-question-groups and an excerpt of it is copied below.

1) The slider to choose the number of groups (variable x)

Create a ‘Multiple numerical input’ question with Qcode ‘gcount’. The maximum should match the number of random groups within randomization group (‘y’).

Add a subquestion ‘1’. The variable ‘x’ will be stored in ‘gcount_1’.

2) Random groups

Create the random groups: ‘randGroups1’ in randomization group.

3) Equation in each random group

Every random group should start with a hidden question of the equation type.

The value of the equation is the sum of the RelevanceStatuses for all the other groups in the same Randomization group.

4) Questions within a random question group

The trick is that every (visible) question within each random group must have a relevance equation that checks if the equation of the current random group is less than gcount_1 (the ‘x’ variable). The relevance equation is entered in the general options of each question.

Disk2vhd is a utility that creates VHD (Virtual Hard Disk – Microsoft’s Virtual Machine disk format) versions of physical disks for use in Microsoft Virtual PC or Microsoft Hyper-V virtual machines (VMs). The difference between Disk2vhd and other physical-to-virtual tools is that you can run Disk2vhd on a system that’s online. Disk2vhd uses Windows’ Volume Snapshot capability, introduced in Windows XP, to create consistent point-in-time snapshots of the volumes you want to include in a conversion. You can even have Disk2vhd create the VHDs on local volumes, even ones being converted (though performance is better when the VHD is on a disk different than ones being converted): https://docs.microsoft.com/en-us/sysinternals/downloads/disk2vhd.
