The data were collected from a statistics class. The column head gives the variable, and each of the other rows represents a student in the class. Explain why the variable Male, is categorical, even though its values are numbers. Often, it does not make sense, or is not even possible to add the values of a categorical variable. Does it make sense for Male? If so, what does the sum represent?
