A user seeks the original 1996 paper 'Using the Self-Stated Importance Questionnaire to Interpret Kano Questionnaire Results' by Fong, which describes a statistical test widely referenced for evaluating Kano surveys but difficult to locate online. They question whether the commonly cited two-proportion z-test is statistically appropriate for Kano data, which comes from dependent rather than independent samples, and want to consult the original source to understand the test's theoretical basis.
