Filters are a key analytic feature in any project.
Researchers can make their own filters on the fly using the drop-zones. They can also make more complicated features using the Filter Builder (ie: in line with Boolean logic).
A data processing department may choose to set up a variety of filters in a dataset in advance of the researcher working in Crunch.
Note: Unlike other software, a filter is not stored as variable in Crunch. It is a construction that is derived from variables and not a variable itself. The Filter Builder can be used to Save A Variable from it (with values of 0's and 1's), but a filter itself in Crunch is not a variable.
