Agglomerative hierarchical clustering (AHC) analysis of overall quality.

Class		C1	C2	F1	F2	F3
1	28		3.82 ± 1.6	3.57 ± 1.4	4.89 ± 1.6	5.32 ± 1.6
2	43	5.95 ± 1.5	5.23 ± 1.4	4.81 ± 1.7	4.09 ± 1.2	4.51 ± 1.7

subjects were removed from AHC analysis because they marked same ratings for entire samples. superscripts within a row meant significant difference at < 0.05 by Fisher’s least significant difference test. subscripts within a column meant significant difference at < 0.05.
