Cost page

This page of the sample design dialog allows input and analysis of costs associated with the sample design.

This design page contains the following controls:

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 User’s Guide.
