Missing Data Codes

Fields that have blank/ missing values may be marked with a custom Missing Data Code to indicate why the value is blank. This can be used in data analysis to specify why a field lacks a value.

Missing data codes can be used for any field type (e.g., date, slider, file upload fields). Since a missing data code is saved as the field value, this means that the field's missing data code can then be optionally exported in a data export or viewed in a report (if you so choose - this is an option when creating a report).

Missing data codes can also be utilized in branching logic. The isblankormissingcode is a new function that was created to handle missing data codes. This function will provide a binary response, where 0 is false and 1 is true. An example statement is included below, in which a field will only appear if ‘field_name' is blank or has a missing code:

If you would like a field to appear when ‘field_name’ is not blank, please use the following statement:

To utilize Missing Data Codes, the feature must be enabled in the Project Settings.
