Abstract
ASSESS
A computer-based tool for statistically assessing measurement errors in the collection of soil samples. Users can input and save information on quality assessment data, historical data, sampling considerations, and data quality objectives. ASSESS evaluates and displays errors at critical steps in the sampling and measurement stages from quality control/quality assessment data. ASSESS displays total measurement error as well as errors (i.e., variances) for the sample collection, subsampling, transportation and handling, and analytical stages. Users can perform mathematical transforms of the data and view plots. (The hypertext document "Rationale for the Assessment of Errors in the Sampling of Soils," by J.J. van Ee, L.J. Blume, and T.H. Starks, provides background on the use of this program.)
