I am conducting an experiment in which participants are presented with moral scenarios. There are 5 distinct conditions, each with 15 different versions. For each participant, I aim to randomly display a total of 50 scenarios, ensuring that 10 scenarios are selected from each condition. Additionally, I want the order of these scenarios to be completely randomized.
For example:
ScenarioType_IncidentalSelf -Dilemma #5
ScenarioType_IncidentalOther - Dilemma #9
ScenarioType_InstrumentalSelf - Dilemma #13
ScenarioType_InstrumentalOther - Dilemma #3
ScenarioType_Filler - Dilemma #8
ScenarioType_InstrumentalSelf - Dilemma #1
ScenarioType_IncidentalOther - Dilemma #7
ScenarioType_Filler - Dilemma #12
ScenarioType_InstrumentalOther - Dilemma #2
ScenarioType_IncidentalSelf -Dilemma #9
ScenarioType_Filler - Dilemma #2
ScenarioType_InstrumentalOther - Dilemma #10
ScenarioType_InstrumentalSelf - Dilemma #4
ScenarioType_IncidentalSelf -Dilemma #1
ScenarioType_IncidentalOther - Dilemma #15
and so on…
Any suggestions?
Thank you.

They are the same question, but there are technically 3 questions:
A timer
The scenario, each with the same multiple choice question
A slider question
I have 75 blocks, each with these 3 component, the only thing that differs is the scenario.
So, an easier way to do it would have been with one loop & merge block proceeded by 6 multiple choice questions (5 on one page, 1 on its own page) hidden with JavaScript to do the randomization.
Since you’ve already built all the blocks, you can do 5 randomizers to set embedded data field flags for each scenario/dilemma combo (in each you’ll display 10 of 15 evenly presented). Then you’ll have one randomizer to display all the selected blocks. It will look something like:
What type of question or questions does a scenario consist of? Is each scenario the same question(s) with only different scenario text and/or image presented or is/are there unique question(s) for each scenario?

@TomG - I am always looking for more efficient ways to do things in the future. Could you share the JavaScript solution or is there somewhere I might find an example?

The JavaScript part of the solution is trivial - either hiding a question or clicking the next button is one line of code.
The trick is in setting up the multiple choice questions and the loop & merge. In a block before the loop & merge, the first 5 MC questions would have 15 dilemmas as choices, and you use Advanced Randomization to display 10 of 15 evenly presented. The 6th MC question is on the next page, it has all 75 randomized scenarios/dilemmas as choices with choice display logic on each choice based on whether it was displayed in the question on the previous page. Then the loop & merge is based on the displayed choices in the 6th multiple choice question. That gives you one loop for each scenario/dilemma (75) with 50 randomly displayed. Set up your loop & merge fields with whatever you need piped into the questions for each scenario/dilemma.
