Summarise one descriptive attribute across the panel: mean intensity, sample standard deviation, and range on the scale used.
Try sample values — fills the form with the worked example below.
–
Mean intensity
–
Standard deviation
–
Range
Equation: Mean = Σ scores ÷ n; SD = √(Σ(x − mean)² ÷ (n − 1)); Range = maximum − minimum.
Method: ISO 13299:2016 descriptive profiling; panel mean and sample standard deviation per ISO 5725-2.
Assumptions: Scores are on one consistent intensity scale; each score is one panellist.
Limitations: A single-attribute summary only — it does not test whether samples differ; use Tool 227 or an ANOVA for that.
Rounding: Mean and SD to 2 decimal places; range as entered; intermediates unrounded.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.
