[UAI] About Data Analysis

[Jos�]

Hi,

        I'm help a friend who's working in analysis
of business data. The data was acquired from a questionnaire.
Each question has a set of answers and the the user marks
one of that. Futhermore, the answers are made in some way
that the second involves the first, third involves the
second, and so on.
        I wold like to know if is correct treat this data
how mutually exclusive. If it's incorrect could any one 
gimme some suggestion.

        Thanks!
