Fuzzy Nonbalanced Hedonic Scale (F-NBHS): A New Method for Treatments of Food Preference Data Collected with Hedonic Scales of Points

Table 1

Central values for each category in the 9-point fuzzy nonbalanced scale.

Number of points in the scale (t)	K = (t + 1)/2	n	Categories depending on the scale area	Formula used	Value of the central point of each category
9	5	−4	Lower extreme	Sn = k + n	1.00
		−3	Intermediate	Sn = k − (|n| + (1/k))	1.80
		−2	Intermediate	Sn = k − (|n| + (1/k))	2.80
		−1	Intermediate	Sn = k − (|n| − (1/k))	4.20
		0	Central	Sn = k	5.00
		1	Intermediate	Sn = k + (|n| − (1/k))	5.80
		2	Intermediate	Sn = k + (|n| + (1/k))	7.20
		3	Intermediate	Sn = k + (|n| + (1/k))	8.20
		4	Upper extreme	Sn = k + n	9.00
