10. DataWolff
DataWolff™ is a general purpose data analysis
program for streamlining Excel-based data
analyses.
The program functions as follows:
User enters test data in a text file, or establishes
a connection to a coal analysis data base.
User starts the program and is prompted for
which test to run, which parameters to analyze,
and which data file to analyze.
The software then runs automatically and creates
an Excel Workbook that contains a detailed test
report workbook which contains calculations,
tables of numbers, and plots.

ASTM D6518 Analysis Script
Lab data as .csv file
ASTM D6518 Calc. Library
and DataWolff General Calc.

13. The calculations performed in each of these analyses
closely follow and are described in the ASTM test
procedure ASTM D 6518 – Standard Practice for Bias
Testing a Mechanical Coal Sampling System.

15. Review of DataWolff Bias Test Software
by C. H. Proctor
“I have run the software on examples provided. Even
for a novice with Excel like myself, the code works
easily. We first ran the ash-Btu example from Table
A2.12 of D6518 and I must say the graphics are a joy to
behold. The software is an undoubted success. It was
designed to allow practioners to run Hotelling’s T2.
Mr. Hotelling would be proud.”
