Sample Options.
Sometimes, you don't want to show all your options, you only want to show a random subset of your list of options to respondents.
To do this, you can use the "Sample" feature to randomly select a specific number of choices, statements, or questions to be shown to each respondent.
This is similar to least filled tags except "sample" is random whereas "least filled tags" are based on lowest count. See related article: Add Least Filled Tags vs. Retain Least Filled Tags
