I am preparing a CBC study, where I want to test if the attribute importance (or range) of two attributes differs significantly (e.g., Attribute 1: 8.xx%; Attribute 2: 9.xx%) within one sample.
Is there a usual way to conduct this test (e.g., a t-test to complare the mean range/importance, or HB procedure)? I was wondering if this works similar to testing significant differences between two attribute levels within one attribute?
Furthermore, as I could not find a description of this test in the book or forum, I am wondering if this is a valid approach.
Thanks in advance!
