(Continuing) Revising our committee’s TOR
So far we have 3 versions, 1. Original/old, 2. Mike, Paul, Qian were
working on the old version and made some changes and has an
unfinished version, 3. Deb. worked on the old version and made some
changes so it is also an unfinished version.
So we will need to discuss all the changes and to add all the changes the
committee selected to produce a new version.
(Continuing) Statistics Advisor Review form
(Robert, Caryn)
The committee has decided to modify the form on the AOAC web into 2
separate forms for Quantitative, and Qualitative. Robert and Caryn are
taking lead on the new forms (Qualitative and Quantitative). All comments
are welcome.
Sidney will look up the old emails and gather files and we can resume this
work.

Scott: wants to add intermediate precision on Appen J
Scott:, over last 2 years, ISO has applied some methods using different
labs, different times, different analysts, etc, but how to pool data
together
ISO called this “Intermediate Repeatability”, and reproducibility, it is
very confusing.
We need guidance.
Scott: OMB: Paula Brown at BC Institute of Technology volunteered to
help.
Robert: use effect, not repeatability, and reproducibility.
Paul: ISO 5725 part 4, part 6, done everything, incl. all definitions.
Jane: If you have the targeted uncertainty then you have an idea on
how to measure this. Jane said she can help.
Scott: Robert, Paul, Jane, Paola Brown, Scott, we will hold a T-con in
Dec. for about 2 hours.
Sidney asked if he could join. Scott said he wants to keep the group
small, but since Sidney is chair, so it is OK. Delia will send up the call.
Membership: Delia will discuss this next call.
