A.1.2 Points of Nonconsensus

There were subjects on which the statistics workgroup was unable to reach consensus. The most significant of these regards the M-3 simulations presented in Section A.5. Some members of the workgroup were of the strong opinion that these simulations addressed the bulk material sampling nature of ISM and Gy theory in ways that the other simulations did not and make an important contribution to understanding of how sampling patterns affect ISM performance. Other members of the workgroup held the strong opinion that the methods for these simulations and their interpretation of these simulations are flawed, specifically in terms of how the "true" mean is defined. To aid the reader in understanding the basis for this disagreement, the contrasting viewpoints are presented on the following pages.
