An investigation of the association between drink preferences and the color of teeth is proposed. Subjects will be surveyed as to the type of drink most often consumed (coffee/tea, juice, caramel soda, water, or milk). A clinical exam will be performed after dental cleaning to determine the color of the teeth (reddish brown, reddish yellow, gray, reddish gray). Discuss the most appropriate methods for describing the data (graphically and numerically). What statistical method would be the most appropriate for addressing the research question?

I need explanation methods in full description and with given example.
