Fig. 7. Index values of both samples, IA compared to the DB. Sample 1
(a)—the L/T index is larger for the DB than for IA whereas the other two
indexes are nearly identical. Sample 2 (b) DB results are somewhat less
than IA for the L/T index. The W/T index is identical for the two but the L/W
index differs, the DB results are less than the IA.
