In this chapter, the newly developed team will raise multiple research questions that will address issues which may be of concern to the political campaign. The team will also learn that some of the assumptions necessary for parametric tests have been violated in gathering the data. Several tests will be utilized to determine whether or not other assumptions have been violated. Research questions that are addressed in this chapter include the following: (1) Are the data Normally Distributed? (2) Are the data random? (3) Do the data have homoscedasticity? The conclusion that the team reaches is that parametric tests should not be used in this situation because of the type of data that was collected and the way that data was collected.
