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 |
