Plan a balanced serving order: total servings, servings per sample, servings per panellist, and the number of possible orders per panellist.
Try sample values — fills the form with the worked example below.
–
Total servings
–
Servings per sample
–
Possible orders per panellist
Equation: Total servings = samples × panellists × replicates; per sample = panellists × replicates; possible orders = samples! (factorial).
Method: ISO 6658:2017 sensory methodology — balanced and randomised presentation order to control order and carry-over effects.
Assumptions: Every panellist receives every sample the stated number of times; orders are drawn without replacement from all possible orders.
Limitations: Planning counts only — the tool does not draw the random order itself; draw it from a random-number table or generator.
Rounding: All counts are whole numbers; factorial shown exactly for up to 12 samples.
This is a calculation aid, not a laboratory report — confirm against your accredited method before citing a value.
