This page of the sample design dialog allows input and analysis of costs associated with the sample design.
Total Area to Sample 
Displays the total area of selected sample areas on the map. If no map is being used, this control allows you to input a theoretical sampling area. 
Units 
Units associated with the inputted sampling area. 
Sampling Costs 

Fixed Planning and Validation Cost 
This is the fixed cost associated with the design. This amount does not change with the number of samples. 
Field Collection Cost per Sample 
This is the cost associated with collecting and preparing the sample for delivery to the analysis laboratory. 
Analytical Cost per Analysis 
This is the cost associated with the laboratory analysis. 
Total Cost 
This is the total cost for the sampling design, using the formula: Total Cost = (Fixed Planning and Validation Cost) + (Field Collection Cost per Sample) * (Number of Samples) + (Analytical Cost per Analysis) * (Number of Samples) * (Replicate Analyses per Sample) 
Cost Comparison 
When using the MQO option 
Method A Analytical StdDev 
This is the standard deviation associated with the sample analysis for the Method A analysis (taken from the main design page). 
Method B Analytical StdDev 
This is the standard deviation associated with the sample analysis for the Method B analysis. 
Method B Analytical Cost per Analysis 
This is the cost associated with the laboratory analysis for the Method B analysis. 
Cost comparison table 
This table displays the number of samples and total cost associated with Method A analysis and Method B analysis for the 1, 2, and 3 replicate analyses. The combination that is highlighted in blue is the one with the lowest overall cost. 
For an illustration of how to analyze costs, please refer to section 5.4 in the VSP Userâ€™s Guide.
