Restricted Data Approaches: Tables
•If information is collected on a
census, one way of preserving confidentiality is to only release
tables based on a sample.
•Regardless of whether the data
are a census or sample, the cells in a table should not be "too"
small (some agencies require a minimum of 3 entries per
cell while others require 5).
This leads to the method of “cell suppression.”
