Table 1.

Four comparisons of hypothetical filtration methods A and B with fixed median recovery and coefficient of variation and varying rank based on median recovery

Filtration method (fixed) Median recovery (fixed) CVa (fixed) Rank based on median recovery (varying) RCV Best method (i.e., lower RCV)
A 20 0.30 2 0.60
B 68 0.45 1 0.45 B
A 20 0.30 3 0.90
B 68 0.45 2 0.90
A 20 0.30 4 1.20 A
B 68 0.45 3 1.35
A 20 0.30 5 1.50 A
B 68 0.45 4 1.80
a

CV, coefficient of variation.
