Make a Scrambled Collection

1. Select the collection whose attribute values you would like to scramble. (It doesn't make much sense to do this unless there are at least two attributes in the collection. Usually, there is a measure whose sampling distribution you are interested in.)

2. Choose Collection | Scramble Attribute Values.

By comparing the case tables for the collections, it's clear that the first of the attributes has had its values scrambled. The inspector for the scrambled collection has a Scramble panel (see Scramble Panel) with which you can choose which attribute is the one that is scrambled.
