The "Sample Adequacy" step of the workflow allows the user to verify that the data is adequately sampled and to address issues of over or under sampling. This step wholly occurs in the Sample Adequacy tab which is used to identify and create potential samples, as well as manage existing ones. HPMS Manager offers seven interfaces to assist in reporting samples:

Icon	Name	Used To...
	Create TOPS	Create a Table of Potential Samples (TOPS) based on the data in a HPMS Data Table. All other interfaces in the Sample Adequacy tab cannot be used until this step is performed.
	Adjust TOPS	Merge small segments together based on TOPS items.
	Split Sample by TOPS	Split a sample based on breaks in any of the TOPS data items.
	Check Adequacy	View the number of unsampled TOPS sections, required samples, and current samples for each Sample Panel (Functional System, Volume Group, & Urban Area stratum).
	Potential Samples	Identify and add samples to the Sample Panel.
	Expansion Factors	Calculate and view expansion factors for Sample Panels.
	Sample Risk Analysis	Review current Samples Panels for samples that are at risk of moving to a higher or lower volume group.

There is one additional icon on the Sample Adequacy tab; this icon is the sole item in the Maintenance section. It is:

	Precision Level	Edit the Confidence Level and Precision Rate values used in the Check Adequacy interface.
