Precision Ranking

Maximum Difference Scaling& Q-Sort

Eliminate response bias and achieve precise importance rankings through advanced scaling methodologies that reveal true customer priorities and decision drivers.

Methodology Overview

Methods for Precise Importance Measurement

Maximum Difference Scaling (MaxDiff) and Q-Sort methodologies provide the most accurate ways to measure relative importance of features, benefits, or concepts by forcing respondents to make clear trade-off decisions. Below are details regarding the different types of MaxDiff scaling and Q-Sort used by PROOF Insights, depending on your unique research needs.

Case I MaxDiff

Traditional best-worst scaling where respondents choose the most and least important items from sets, providing clean ratio-level importance scores.

Case II MaxDiff

Offers the ability to evaluate the importance of attributes in the context of a profile that includes multiple attributes and respondents rate best and worst profiles.

Case III MaxDiff

Similar to Choice-Based Conjoint (CBC), respondents compare multiple profiles and rate best and worst for each set of profiles.

Q-Sort Methodology

Structured ranking approach that forces distribution of items across importance categories, revealing nuanced preference patterns and priorities.

Key Advantages

Why Choose MaxDiff?

These methodologies provide superior measurement precision by eliminating common biases found in traditional rating scales and survey approaches.

Eliminates Response Bias

Forces clear trade-offs between options, eliminating scale bias, acquiescence bias, and the tendency to rate everything as important.

No scale bias
Clear trade-offs
Honest responses

Interval-Level Data

MaxDiff produces interval data which can be recoded to ratio-level data (for anchored MaxDiff), both allowing for meaningful insights and comparisons.

Precise measurement
Statistical validity
Meaningful differences

High Discrimination

Provides superior ability to distinguish between items of similar importance, revealing subtle but meaningful preference differences.

Subtle distinctions
Clear hierarchies
Nuanced insights

Respondent Friendly

Intuitive task that mimics natural decision-making processes, resulting in higher engagement and better data quality.
