Qualitative Feedback
AdvancedQualitative feedback is data that conveys a user's experience and reasons rather than a number — from observing their behavior to their own direct words about why they did something.
Quantitative data says “what and how much” but is silent on “why”; qualitative feedback fills that gap. It has two sources that must not be conflated: observational qualitative data that comes from watching real user behavior (such as session replay, where the user does not know they are watched and their behavior is untouched), and solicited feedback the user gives themselves (an on-page survey, a feedback widget, a support message). Both are valuable but carry different biases: observation shows real behavior but not intent; the user's statement gives intent but may not match their actual behavior. The common trap is taking a few loud opinions as representative of all users; qualitative feedback is excellent for understanding “why” and forming hypotheses, but measuring “how many” is the job of quantitative data. The best analyses weave the two together rather than substituting one for the other.
