Collections

In Fathom, collections hold the data; tables and graphs help you view the data. Delete a table or graph, and the data are still there. Delete a collection, and the data are gone.

An empty, iconified collection is an empty box.
When a collection has cases in it, its icon is a box of gold balls. You can copy cases from one collection and paste them in another. Your document can have any number of collections in it.
When you Take a Sample from a collection, the sample cases get put in another collection.
When you Collect Measures, from a collection, the measures get put in another collection. Similarly, when you Stack Attributes, or Scramble Attribute Values, you get new Derived Collections.
When you Create a Survey by adding questions to a collection, you get a survey collection.
When you Create an Experiment by attaching a meter to a collection, you get an experiment collection.
