Sampling in Fathom means to choose some number of cases randomly from a collection and put them into a new collection. The original collection is not changed. The sample collection is a kind of derived collection. There are two ways to sample cases from a collection: Drag and drop or use a menu command.
1. Make a new collection, for example, by dragging one off the shelf.
2. Drag the name of the source collection into the new collection.
The new collection becomes a sample collection.
1. Select the collection.
2. Choose Collection | Sample Cases.
A sample collection is created and filled.
You can control the sampling process in the Sample panel of its inspector (see Sample Panel).
If you Define a Measure, you can collect measures to build a sampling distribution of your measure(s) (see Collect Measures and Other Results).
