Have Qualtrics "select" the youngest person.

How are they entering their childrens' ages? Is it a multiple select question? I'm trying to create a sample question in one of my test surveys to see how this might work....

Kara_C I often ask the respondent to identify this themselves ("Think of your youngest child currently between the ages of 4-11."). This also gives you a chance to provide guidance on what to do if someone had 'multiples' (e.g. twins, triplets, etc.) for which the program would not be able to identify which entry is the youngest (you might recommend the child whose name come first alphabetically, etc.). This will work if you don't need to run analysis on age of the children they are referring to.
Here's a rough sketch of using loop & merge (assuming a max of 5 children allowed in a household but that can be expanded by upping the limit in Q1, adjusting the loop and merge, and repeating display logic in Q3. You can also get rid of Q4 I was using it for testing - e.g. houses that adopt kids both age 6 might need an initial
to distinguish which 6 yo is actually younger.).
This is a "brute force" solution if you are in a time crunch. But I recommend being patient to see if other Qualtrics Community members can give you an actual solution where Qualtrics does this for you.
Youngest_child.qsfAnother way to do this that might be easier for the programming is to ask how many children they have that is each age. And then Survey Flow logic can be used to identify the youngest age between 4 and 11. (I've made the logic equal to 99 if there are no children between 4 and 11). This is tedious though, so weigh carefully what is best for the respondent.

Kara_C wow, that sounds like a ton of work but I'm glad you figured it out! 🤗
