This is a tool that is located on the Sample Adequacy section of the Sample Adequacy tab. 

Function

The Check Sample Adequacy interface () is used to view the number of unsampled TOPS, required samples, and current samples for each stratum (Functional System, Volume Group, and Urban Code grouping). The user must Create TOPS before working with this interface.

Controls

This interface hosts the Data Table dropdown control, alongside these controls:

Table Elements

This interface also hosts some Table Elements: 

Control	Used To...
Second Column	Display the precision level (confidence level – precision rate) used to calculate the number of required samples.
Third Column	Display a caution symbol () for insufficient samples or a green check mark () for adequate samples. The number beside the caution symbol denotes how many stratums are deficient.
Volume Group Columns	Display three numbers.

Cell Information

Each cell under the Volume Group section of the table contains three numbers:

1. The number of unsampled TOPS Sections -- the number of TOPS locations that do not have a Sample ID for the stratum.
2. The number of required samples -- the number of samples needed for this sample stratum.
3. The number of provided samples -- the number of TOPS locations that do have a Sample ID for the stratum.

The first number will appear as a link that opens the Potential Samples interface. This allows the users to easily add samples to a stratum with an insufficient number of samples (denoted by the third number in a cell being red). Below is a visual that shows each number type and style on a sample Volume Group cell.
