listVar

The listVar function iterates through a list and returns the variance of all evaluated statements.

type: text

Details

• In its most basic form, listVar accepts two inputs: a list name and a field reference constructed with the '[id]' placeholder. 
• Options can be filtered in or out of the list with inclusion/exclusion syntax.
• listVar can be used in conditional logic with tags such as showif, termif, cvalue, and failif.
• When multiple lists or conditions are used, the list name is prefixed to the [id] reference and separated by a colon, (e.g., [LISTNAME:id]). Prefixing clarifies list references and is necessary for the software to iterate and sum calculations across different lists.
• Though not explicitly tied to tables, table references are imagined to be the most common usage.

Additional examples

In this example, we place the listVar function on the failif tag to evaluate the table's variance. If a respondent "straightlines" by selecting the same answer choice for all rows, the failif tag triggers CheatSweep to lower their score.
