Displaying a set of question groups in random order is easily done by following these steps:
1. Identify the question groups you want to display in a random order.
2. Think of unique group name label you'd like to use to identify the set of questions groups to randomize: let's say we use randgroups
3. Edit the first question group to add to this randomization group
4. Enter your group name label into the Randomization group field as shown below, then save, and proceed to repeat the same for each question you want to include in that randomized group (remember to use the same group name label to associate the groups together):
