How do market researchers use a Q-spread?
Market researchers use a Q-spread to analyze how respondents rank or sort a set of stimuli, such as product features or brand messages, along a distribution grid. The shape and concentration of the spread highlight areas of consensus or polarization. Researchers then examine these patterns to extract factors or segments that represent distinct consumer mind-sets. These insights help tailor communication strategies, identify positioning opportunities and uncover emotional or attitudinal drivers influencing decision-making.
