Standard Practice for Estimating Thurstonian Discriminal Distances

Importancia y uso:

5.1 Under the assumptions of the model, the Thurstonian model approach to measuring the perceived difference between two samples (whether overall or for a specific attribute) is independent of the sensory method used to collect the data. Converting results obtained from different test methods to d' values permits the assessment of relative differences among samples without requiring that the samples be compared to each other directly or that the same test methods be used for all pairs of samples.

5.2 Thurstonian scaling has been applied to:

5.2.1 Creating a historical database to track differences between production and reference samples over periods in which different test methods were used to measure the difference,

5.2.2 Comparing the relative sensitivities of different user groups and consumer segments,

5.2.3 Comparing trained panels that use different measuring techniques,

5.2.4 Comparing the relative sensitivities of consumers versus trained panels,

5.2.5 Comparing different methods of consumer testing (for example, CLT versus HUT, preference versus hedonic scales, etc.), and

5.2.6 Comparing different discrimination test methods.
