Hello, here we have a question about the unacceptable and must-have data in ACBC.
In some respondents’ data, the sections of both must-have and unacceptable questions are blank without data. A few respondents’ unacceptable sections have data but must-have sections are blank. Plus, some respondents only have one must-have question with data and the other must-have section is blank without data.
Can anyone have some explanation for this? For blank sections of both must-have and unacceptable, is this means the respondent does not have preferences in screening and has marked every product as “a possibility for me”? Is it better not to include this kind of case (marking every product as a possibility) in data analysis?
