Regarding the overall quality obtained by applying the weighting
factors, the samples were placed mainly from the middle of the scale to
the upper scores. In fact, 81.1% of the samples was between 2.76 and
4.25, corresponding to medium-high quality. Minimum and maximum
quality global scores were 1.98 and 4.61, respectively. The difference
on the scale is 65.8% of the maximum difference possible (4 units: 5–1)
and demonstrates the suitability of the method to differentiate among
samples according to their quality.
