Note: the "Not Equal" Operator: This does not take into account un-responded questions. It essentially is an "OR" between all the other options except for the chosen answer.

Multiple criteria segmentation is a mechanism to allow for data segments across multiple questions. For example if you want to segment data based on age and gender -- you would use the multiple criteria segmentation tool. You can use AND/OR logic for multiple criteria segmentation.

For example, you could create a data-segment/logic criteria where Gender = Male OR AGE > 25 etc.
