Analyse 9-point hedonic liking scores: mean, median, the share who liked the sample (7–9) and the share who disliked it (1–3).
Try sample values — fills the form with the worked example below.
–
Mean liking
–
Median
–
Liked 7–9 (%)
Equation: Mean = Σ scores ÷ n; median = middle score; Liked % = count(7–9) ÷ n × 100; Disliked % = count(1–3) ÷ n × 100.
Method: ISO 11136:2014 hedonic testing with consumers in a controlled area; 9-point hedonic scale.
Assumptions: Scores are whole numbers on the 1–9 hedonic scale; each score is one consumer.
Limitations: A mean alone hides bimodal liking — always read the liked and disliked shares with it.
Rounding: Mean and median to 2 decimal places; 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.
