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?

O A. Male is categorical with one category. Its variable coding rule is that 1's represent males and 0's do not represent anything.
O B. Male is categorical'with two categories. Its variable coding rule is that 1's represent males and O's represent females.
OC. Male is categorical with two categories. Its variable coding rule is that 1's represent females and O's represent males.
Does it make sense to add the values of the categorical variable Male? If so, what does the sum represent?
O A. It makes sense. If the numbers are added, the sum is the number of males.
