What is "Sample Choices", "Sample Statements", and "Sample Questions"?
Sometimes, you don't want to show all your choices, you only want to show a random subset of your list of choices 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: What is "add least filled tags" and "retain least filled tags"?
