Find What Matters Most
MaxDiff analysis (Maximum Difference Scaling) is the most reliable way to rank consumer priorities. By forcing trade-offs between items, MaxDiff eliminates the scale-use bias that makes rating questions unreliable and produces a true priority ranking.
How MaxDiff Works
Respondents see sets of 4-5 items and select the most and least important in each set. Across multiple sets, every item competes against every other, producing a ratio-level importance score.
Common Applications
- Feature prioritisation — which product features drive choice?
