Score one panellist: discrimination accuracy, repeatability across replicates, and the combined performance score.
Try sample values — fills the form with the worked example below.
–
Accuracy (%)
–
Repeatability (%)
–
Combined score (%)
Equation: Accuracy % = correct ÷ trials × 100; Repeatability % = agreeing pairs ÷ replicate pairs × 100; Combined = (accuracy + repeatability) ÷ 2.
Method: ISO 6658:2017 sensory methodology; ISO 8586 panel performance monitoring.
Assumptions: Trials are independent discrimination tasks; replicate pairs are the same sample presented twice.
Limitations: One panellist at a time — panel-wide performance needs every panellist scored the same way.
Rounding: Percentages to 2 decimal places; intermediates unrounded.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.
