Herman Bauer, Geri Blakey, Georganne Bowman, Chad Ferguson, Bob Goulding, Mark and David Kuechenmeister, Armand Matthews, Vicky McAlister, David Murray, Carol Pollard, Marc Ramsey, Marion Traynor, Howard Webb, Dan Wollaeger

The scatter plots to the right show results of Split Samples (1998-2009).

Volunteer-collected samples are shown on the vertical axis, MU staff-collected samples are shown on the horizontal axis. The dotted line represents a perfect 1:1 relationship (R2 = 1.00).
